So it's been a while. I've been keeping busy. I'll give you a quick recap on the last month or so:
1. A month ago, I was blind and couldn't walk. Not joking, and only exaggerating a little bit. After a trip to the emergency room, I was diagnosed with a sort-of rare kind of vertigo. I can now see and walk, but sometimes the earth suddenly shifts and I'm the only one that can feel it. I've been prescribed anti-dizzy medication (which I think is just anti-histamine on speed; mind you, not anti-histamine with speed - on speed. with speed would be a totally different story), but it makes it nigh impossible to pee and I can't stand and salute (if you know what I mean), so I don't take it.
Highlights of my $4200 emergency room visit include the super hot nurse (and seeing down her shirt being the first thing I saw when my sight came back - there is a God), the picture my niece drew for me (green squiggles), and the fact that all the nurses were placing bets on what was wrong with me because (aside from sight and walking) I was completely and totally healthy in every way.
So now my vision sometimes goes a little blurry and I stumble. I can live with that.
2. My boss fired me because I couldn't see or walk. He is also my brother-in-law. He's also an asshole.
3. The drive from Oakland to Buena Vista is normally done in 4 days. I did it in 2 1/2. After getting to Utah, I stayed at my parents' place. The next morning, I picked up my friend Christina, and we drove to BV without stopping ('cept food and gas). We switched turns sleeping and driving. It was absolutely wretched and I hope to never do it again. The highlight of the trip was not being able to cross the Missouri river because it was flooded, so we decided to just drive around it. Think about it.
4. I've lost like 25 pounds since the beginning of summer. My goal is to get myself down to my Dominican weight. Only 10 to go.
5. Now I'm at school and I'm only taking 6 credits, so I have lots of time to think and stuff. It's nice because I only need to budget 1 library day a week, rather than 3. And that 1 library day only really lasts for 45 minutes, rather than 3-4 hours.
Today while in the shower (like 10 minutes ago), I came up with a thought that I have never thunk before (hehe). It's the Blank Slate Concept. First, I'll explain the back story to it:
I live in a different place this year. A much cleaner, nicer, carpeted, amazing, huge, less Pentecostal house. I have 3 housemates. One of them, Brady, is a guy that I've known for like 6 years. Brady was here over the summer. During the summer, Brady and Sara 2.0 discovered each other (and Brennon was mad at Brady for dating her - a fact that I found humorous. if you don't know why, read back a couple posts). They dated. When I heard, I knew that it was only going to be a summer thing.
At SVU during the summer, you become friends with people that you wouldn't normally be friends with. When the new semester starts, you leave your summer friends and never talk to them again. I just extended that social fact to dating and I was right. Except that Brady and Sara 2.0 each have emotional dependency problems, so they're having a tough time fully letting go. Basically, Sara 2.0 still wants it and believes she's in love (she's not) and Brady says they're friends but treats her like a girlfriend. It's such an interesting situation that I'm writing a song (and a blog post) about it. Sara 2.0 stays the night sometimes, but has her own bed (oh yeah, we just have random beds everywhere in our house - like as furniture) in the kitchen. At first I was a little weirded out by it, but I've gotten used to it. Sara 2.0 and Brady are still around each other all the time, but not in a relationship kind of way. It's a stupid situation and Sara 2.0 realizes it, but still rolls with it (she's starting to come around, though, and has been actively keeping herself from being around him the last few days).
I am very familiar with this scenario. I've been on Brady's side many many times.
So now I spend lots of time around Sara 2.0 - the girl that I (kind of) dated a year ago. Basically, she uses me as an excuse to come over, and then leaves and hangs out with Brady when he comes home. If he doesn't notice her, she starts flirting with me hardcore until he notices and gets jealous, then she goes and hangs out with him.
Is it weird? Sometimes (and my 'sometimes', I mean 'hell yes'). Is it bringing up past feelings? Not really (I still care about her as slightly-more-than-a-friend [as I do about most of my exes], but not enough to ever want to be in a relationship with her - a stance that I shared with her last night). Much to my initial dismay (and mostly because I thought her friends would always be over here too and I hate them), we have decided to become friends again. We most likely wouldn't be actual friends if she weren't over here all the time trying to win Brady back (but I don't tell her that). It's a way for me to be informed and interested in the situation without actually stepping in and asking questions. And I like knowing everything.
I'm actually impressed with how she's changed over the last year. She's matured the equivalent of 3 years in 1. So that means that instead of being 16, she's now 19 (and still has 1 year to go to catch up to her actual age).
Since she's not quite the same person, we will now call her Sara 2.1.
Her and I have talked a lot about how we used to (kind of) date and what we were each thinking when that was going on. It was interesting to hear her thoughts on the matter. Basically, she admits that she was stupid and totally into her friends, but also wasn't sure she wanted a relationship with me - all views that I also had. We've clarified that we do not want to be in a relationship with each other, but do enjoy being around each other and flirting and cuddling and all that. It's basically a friends+ arrangement. She's still as cute as ever and can still make me laugh, and there's something about her that makes me feel calm when she's around, but my experiences with her tell me that being in a relationship with her feels like trying to inflate a tire with a big hole in it.
Then I came up with the Blank Slate Concept.
How would I react if Sara 2.1 were herself, but a different person?
Ok, that's kind of confusing, so let me try again: What if you completely erased my memory of her - all my experiences and thoughts and and knowledge and all that - and then I were to meet her (Think Eternal Sunshine). What would I think of her? My opinion of her would likely be entirely different.
Hold on, there's a girl in my house that sounds like she's completely shitfaced and it's a Sunday afternoon. I must look into this. (where are my pants?)
It was exactly who I thought it was. I love knowing everything.
K, back to Blank Slate Concept.
What if I were to meet her now instead of a year ago? Would I still find her attractive (probably)? Would I try to date her all over again (probably)? Would it last this time (I don't know - maybe)?
Then I extended this concept to all of my friends. Would I even be friends with some of my friends if I met them for the first time just yesterday? Would I be better friends with them if I met them just yesterday? Would I be super attracted to some of the girls I'm friends with? Would I try to date them? It's a super interesting concept to me and I really want to sit down with someone and just talk about what we would think of each other if we were to Blank Slate, but the problem is that it's such a potentially uncomfortable conversation that it will likely never happen. I've only met one person that I can think of that could possibly handle such a conversation, and she's Canadian.
But think about it. How would you treat someone that you're close with if you met them for just the first time right now? Would you even pay attention to them or realize that they're there? Would you fall in love with them?
Then I started thinking in 4D and it made my brain hurt.

okay... So in thinking about this in reference to you and me (which wasn't ever a thing, thank heavens) and being friends(which I'm very glad we were)I'm not really sure we'd be friends now. But that's just because of proximity and a divergence of interests. Now if you lived nearby and I was still in school... I'd probably still invite you over for dinner and allow you to corrupt my (future) children.ReplyDelete

This is a video tutorial on how to create a domed cupcake with a brush embroidery effect on the top. The technique of brush embroidery can be used on cupcake or a normal cake and looks great for birthdays and weddings.
The technique uses royal icing, I had this in a piping bag with a number 2 tip (sorry I forgot to mention that in the video) and a flat edge paintbrush.
Below is a link to my other video which is a step by step guide to how I make my buttercream.

MIT Media Lab apologizes for raunchy SXSW party wristbands
People attending a South by Southwest party hosted by the MIT Media Lab Saturday night in Austin, Texas, to promote "exciting media innovation projects" were welcomed with raunchy wristbands that sparked outrage among some party-goers.
"That's a nice dress," read one of the wristbands. "It would look great on my floor."
"Do you wash your clothes with Windex?" read another wristband. "Cause I can see myself in your pants."

Fringe sharpening is required to obtain a higher accuracy of measurement. Nonlinear recording and consequently filtering at the higher-order halos for image formation give sharpened fringes in the image. Furthermore, if the apertures during recording are properly arranged, cross-frequency orders appear, which when used for filtering provide moiré fringes of higher contrast due to intercoupling.

Hello! So this story is going to be a little different. I am yet to write a Hunter Clarington fanfic but, I think like many, I have fallen for the charms of the new Warbler captain. This story is a little far-fetched and will only continue as long as people are interested. This is my - I can't keep track - Glee story and I hope that you enjoy it!
This story will look at why Hunter really came to Dalton, his story of being given the scholarship being a lie (in the story) and the boys find out what really happened. For the first few chapters, I hope to establish Hunter's character and write out the scenes that we have seen him in in Dynamic Duets, while the boys find out the truth in the background.
I hope you enjoy it. Obviously, I don't own any characters or songs or whatever that you recognise. This story is dedicated to my incredible friends Magic Of Every Kind and SilverThornFeather as well as my dedicated reader nomorecandles who I apologise profusely to for ending Uniform. Magic has written several awesome stories for both The Avengers, Ratchett and Clank and Merlin. If, like me, you are mourning the loss of a fandom in the last episode of Merlin being aired yesterday evening (way to ruin Christmas BBC!), I would highly recommend her. She is MEGA talented at writing and mark my words, you will see her name on book covers soon!
Also, the quote at the beginning isn't actually a Hunter quote, the story began in the first person and I liked the beginning so much that I decided to keep it. I have a plan for there to be a 'quote' at the beginning of each chapter!
Merry Christmas to all who celebrate it and to all those who don't, enjoy the holiday!
Chapter 1
'Some say that animals, especially carnivores, can smell fear. They can smell when you are afraid, your most animalistic and raw emotions. I think it's the same with boys. They can sense what you are feeling, even your most complicated and buried emotions, ones you may not even know you are feeling.' – Hunter Clarington
He could see them all staring at him. He hated people staring at him unless he was in charge. He was definitely not in charge, and he hated it. There was a perfectly logical explanation for everyone staring at him. He was new. It wasn't exactly rocket science to work out why he was singled out as the new boy. He was the one kid in a combat army uniform in comparison to all the navy blue blazers and red piping. His backpack was hitched up on his back and he stared up at the rising building that was his new school: Dalton Academy School for Boys. He waited in anticipation, waited for the jeers and sneers at standing out in the crowd. But they didn't come. Sure there were a few glances but they were curious rather than accusatory.
"Hey." The word came, the sharp tone that he had been anticipating, was finally audible.
He turned to see a light-brown haired boy of his age striding towards him, a confident smirk on his face. Perhaps he could relax, but something inside him made him stop. Maybe it was the years of training and trials that meant he immediately frowned, adopted a defensive stance and put his bag down slowly, not wanting to have his hands full if he was going to be attacked.
"Yeah?" He asked accusingly. He didn't mean to be so defensive but it was instinctive.
The boy put his hands up in mock defence. "Hey don't worry. You must be our newest transfer, Hunter Clarington."
Hunter looked at the boy in front of him, analysing everything as he had been trained to do. The boy was clearly relaxed, his shoulders back and posture good but he was leaning slightly on one foot and the folded arms were more of a natural stance than a defensive move. Politely, he took off his cap and nodded.
"That's me. Senior and former captain of the show choir at my last school. That is why I am here."
The boy frowned momentarily. "I don't think I understand your last statement fully but I am sure I will in time." He extended his right hand straight towards Hunter. "Sebastian Smythe, senior, deputy head boy and captain of the Warblers. The latter being our show choir here."
Hunter nodded, it was fortunate indeed that he had run into Sebastian as the first person he met; it saved an awful lot of trouble. He took the hand and shook it firmly, admittedly feeling a little weird greeting as such, used to snapping a salute beforehand. He grabbed his rucksack and pulled a piece of paper from the top. "I've been told I'm in Room 412, do you know how to get there?"
Sebastian nodded. "Yeah, of course that make sense for you to be Trent's new neighbour." He started to walk towards the tall building and Hunter fell into step beside him. "All the seniors here are on the fourth floor but there's a lift to take you up there with all your stuff." He nodded to the large rucksack that Hunter had casually slung over his back. "Is that everything?"
His tone was questioning as well as curious and Hunter once more immediately fell back into defensive mode. "No, of course not. My folks are sending more of my stuff over in the next few days." He patted the bag slightly comfortingly. "There's a lot of stuff in there. Where I came from, you learn to put a lot of stuff into a small space." Sebastian nodded, slightly unsure how to respond. "So how have the Warblers done in recent years?" Hunter didn't particularly want to make conversation but he knew he had to if he wanted to put his past behind him.
Sebastian's smile grew, clearly the group meant a lot to him. "Last year we made it to Regionals and the same the year before that. I don't know much about that year or before that as I wasn't in the Warblers then."
Hunter raised an eyebrow. "So are you the only lead Warbler then? And Regionals is all you've ever made it to?"
"Hey," Sebastian retorted immediately, "the Warblers in my sophomore and junior years were amazing. We still are. We've just lost a couple of amazing voices though. I'm not the only lead, Nick Davis who rooms on the other side of Trent is also lead and we did have Blaine Anderson until he left Dalton to join his boyfriend at public at the end of last year." Hunter looked at him incredulously. "Tell me about it. It's gotta be one of the most stupid things he's done, like ever."
Hunter snorted. "I reckon with some persuasion he can come back." Hunter's brilliant and strategic mind was working fast. "What's the age difference between them?"
They had entered the building and Hunter tried not to look shocked at how impressive the inside of the building was. The main entrance hall was a large space with sofas lining the walls and a reception desk to one side. Boys were milling about and corridors lead off to different places all over the room. Sebastian was walking towards a large set of oak doors at the end of the room which Hunter deduced must lead to the room and he quickly caught up with the tall senior.
After a pause, Sebastian answered his question as they waited for the lift to come, Hunter being rather inclined to race Sebastian up to the fourth floor, he knew he would win even with all his gear, it wasn't that difficult. "Kurt has just graduated and Blaine is our age. I believe he wants join Kurt in New York once he graduates." He frowned as the doors opened and a few boys stepped out, nodding to Sebastian in respect and greeting. "Why do you ask? And what did you mean by you're here because of your last show choir?"
Hunter pursed his lips, not sure how to answer the question without making his first enemy. "It's something I need to discuss with all the Warblers. Would it be possible for me to audition and meet them?"
Although Hunter hadn't actually answered the question as fully as Sebastian would have liked, the latter decided to ignore this fact. He was a different guy, no more blackmail or assault or indeed a repeat of what had happened last year. "We have a meeting at 8pm tonight; I'll show you around and take you after dinner." The doors of the lift slid open and the two boys exited the lift, the corridor busy and many boys were milling about. "The senior corridor has its quiet periods but now, just after classes have been let out, is definitely not one of them. Don't worry, the guys are cool." He added as he saw a flicker of apprehension in Hunter's eyes. Suddenly he seemed to spot someone and called over the noise. "Hey Jeff!"
Hunter watched as a blonde haired boy turned and made his way through the crowd who had mostly fallen silent at the arrival of the two boys. The blonde boy had bright blue eyes and a wide, gracious smile. He high-fived Sebastian before grinning at the pair. "Hey Sebastian! You must be our newest transfer Hunter." He put his hand out politely. "I'm Jeff Rivers, head boy here and I think I've got the room opposite from you." Hunter nodded and took the hand, unsure of how to react to his piece of news.
"Hi, good to meet you." He stated lamely, so original.
Sebastian saved him in the awkward silence. "Hunter was captain of his last show choir and he wants to audition for the Warblers. I said we'd do it tonight." He informed Jeff who nodded eagerly.
"Brilliant! There are 14 of us at the moment; it would be good to have a fresh face around in the group." Jeff seemed to be genuinely excited about it as he nodded down the corridor. "Let me show you your room, 412 isn't it?"
Hunter nodded as the boys who had been watching started to talk again, a couple still slightly astonished at the sight of army uniform in Dalton halls. That hadn't been seen around for a while.
Jeff swiped the card on the lanyard he had around his neck on the buzzer by the oak door that had the brass numbers 412 on it. They could hear a click from behind the door and Jeff pushed the door open to reveal Hunter's room.
The room was far bigger than Hunter had been used to. All of a sudden, he had space and luxury. The double bed lined part of the right hand wall of the room and had thick duvets ad fluffy pillows that Hunter wanted to go and squeeze they looked so fluffy. He had a tall wardrobe and a huge chest of drawers covering part of the left wall, Hunter could bet that inside the furniture he would find his new uniform. There was a large mahogany desk at the back of the room with new textbooks and new paper, everything he needed for school life, next to a large bay window with a panoramic view over the Dalton grounds.
"So, what do you think?" Hunter had admittedly completely forgotten that Jeff and Sebastian were still there.
He turned sharply and nodded approvingly. "It's nice, really nice. Much better than my last place." He smiled at that and so did the two boys.
"What do you want to do?" Jeff asked. "We can grab your schedule tomorrow morning and dinner isn't for another hour. Do you want to come and meet some of the other boys, or stay and unpack? We don't want you to be on your own for the first few days so you get used to the place. It's totally your call though."
Hunter observed the two boys. From what he could hear, there was no malice, no spite, no sarcasm in what Jeff said. He seemed to genuinely want to be Hunter's friend. But the last time he had had a friend that had definitely not finished well.
He shrugged. "I think I'll unpack first if that's okay. I reckon I will need a couple of helping hands to work my way around the place later. Thank you Sebastian and Jeff."
The boys nodded. "We'll come back for you in let's say an hour?" Sebastian suggested.
Hunter shrugged and nodded. "Sounds good."
He didn't want to say anything else and the boys weren't going to press him for any other information. Silently, Jeff and Sebastian slipped back outside the room, closing the door on Hunter. "Thoughts?" Jeff asked after a moment, his eyes darting momentarily to the door that they had just closed.
Sebastian frowned. "Definitely straight."
Jeff rolled his eyes with a small smile on his face. "You would notice that thing first of all, wouldn't you Seb?"
Sebastian let a weak smirk pass over features before relapsing into a thoughtful expression. "But there's something I can't put my finger on. He said something earlier about the reason he was here was his show choir but it didn't make any sense. He won't go into any detail about it. And he's turned up in military uniform? What kind of school would have a military kit as their uniform?"
Jeff raised an eyebrow. "A military academy?" His raised eyebrows turned down into a frown. "Why would someone come from a military academy to here unless we had someone needing protection?"
They mused this for a moment. "I don't think it's that." Sebastian spoke after a moment as Nick and Trent joined them. "He's a defence. As soon as he heard my voice, he fell back into a defensive stance. I should know, I've used the same moves before. I don't think he's telling the truth."
"Who you talking about? The Hunter kid?" Trent asked innocently and Nick whacked him playfully over the head.
"No Trent, we're discussing the resident ghost Sir Nicholas De Mimsey-Porpington, the new ghost of the Dalton fourth floor."
"But he's – oh." Trent was about to complain at the fact that ghosts don't exist and point out the Harry Potter reference Nick had made before realising he was being teased. The three boys were grinning at him. "It was always worth checking you know. I agree with Sebastian though, he looks like a lost puppy, much like Blaine did when he arrived here." Nick and Jeff nodded, the three of them remembering Blaine joining them a semester into their freshman year.
"How do I hear the sacred name of our hallowed dearly departed?" A voice floated down the hallway they turned to see the Warblers' secret weapon in Jon Whitely, their resident beat box master.
Nick had to suppress a snort. "Blaine's only an hour drive away at another school, Jon. You make him sound like he's six feet under instead!"
The boy sauntered over to the group, messing up his hair as he usually did a wide smile on his face. "Well seeing as we haven't seen him in a while, you would have thought so quite frankly. When did we last see him?"
Nick raised an eyebrow. "Please don't tell me you've forgotten this summer?" He practically begged and Jon laughed.
"Are you freaking kidding me? How could I forget? This summer was awesome!" His grin was large and boys nodded in assent.
"Still, that does make it nearly six weeks since we've seen him." Trent sighed. "I reckon he needs a visit."
Jeff pursed his lips. "Let's see what we can do. Anyway, let's go over to my room and see what we can sort out."
And from behind the door, Hunter took his head off the door where he had been leaning again, quickly affixing his tie that he had been putting on when we had heard the name of the Gryffindor Tower ghost. He was glad to hear he wasn't the only Potterhead here, perhaps even some fellow Slytherins on Pottermore.
Casting the thought of Potter madness aside, Hunter mused about their potential finding. He had lied to Sebastian; he really did have that much in his backpack. Sure the whole thing of learning to pack small was true, but he hadn't packed much, he hadn't had time. It hadn't taken him more than a minute to get himself orientated in his room and putting what he had grabbed into various drawers and putting others on top of drawers and counters. He felt comfortable in his new uniform, the blazer was a perfect fit and he liked it much better than his military gear. Still, Hunter took off his cap and deftly detached the pin from the top before fixing it to his lapel. He couldn't lose his roots, not just yet.
Checking himself momentarily in the mirror to see if his hair was neat enough, Hunter turned and walked towards the door of his room. It was time to leave his past behind and start a new future, one that had no bullying in it and one that finally involved him being in control. He had to have control, and he had to have the best. And now, the best started with the Warblers and a certain seemingly Dalton legend.
Is anyone else on Pottermore? Don't you just LOVE it?! I'm a Ravenclaw, the smallest house and I kinda hazard a guess at Hunter being a Slytherin...What did you think?

5 Preface The activities and achievements of our encounter at Bled 1 can be easily summarized.wewerecaughtinaresonance!however,therewasalsonoshortageof interesting background. We learned many things about the development of analytical methods for the search of resonances and for implementing the influence of nearby thresholds and interferences in the determination of resonance parameters. In many cases, the interplay between quark and mesonic degrees of freedom is particularly significant, for example in the (17) resonance. Resonance parameters, especially poles in the complex energy plane, can sometimes be better determined from the calculationofthetime delayinsteadoftheshapeof theresonancecurve.itwas a great encouragement that nowadays Lattice QCD can be used as well to calculate phase shifts for the pion-meson scattering, even in the resonance region. New mesonic resonances deserved particular attention. One of our experimental colleagues from Belle reported the results on the hypothetical excited states of charmonium, dimesons and tetraquarks. We heard also the prediction that some higly excitedstatesofdandbmesons might betetraquarks,aswellasproposals for its experimental verification. There is also some interesting progress in speculations about hadronic molecules DN and BN. New double polarizaton measurements in Jefferson Lab have clarified several features of the spin structure of 3 He and of resonance parameters in electroproduction of pions on nucleons. The description of baryon spectra, their electroweak structure and decay widths has been successfully extended to hyperons and charmed baryons. There has been noticeable progress in the classification of high-lying baryonic multiplets (N = 3) using the expansion in 1/N c and the O(3) SU(4) symmetry; in the description of pionic and photonic reactions by using coupled channels; in the scattering of a superheavy hadron which might be a candidate for dark matter. As a surprise came the recently discovered magnetar which is too heavy to be supported by quark gas or plasma in its core. This suggests that the three-quark cluster should be stable also at five times the nuclear density, extending the nuclear equation of state into this region. Asyou cansee,thereis noshortageof problemsandsurprises,butalsothe strategyofasequenceofsmallstepscanbefruitful!thereforewehopethatourtraditional Bled Workshops will be continued.

7 Predgovor Aktivnosti in doseˇzke našega letošnjega blejskega druˇzenja zlahka povzamemo. Ujeli smo se v resonanco! Pa tudi zanimivega ozadja ni manjkalo. Seznanili smo se z razvojem analitskih metod za iskanje resonanc in študijem vpliva bliˇznjih pragov in interferenc na določitev resonančnih parametrov. Ponekod je izrazito pomembna povezava med kvarkovskimi in mezonskimi prostostnimi stopnjami, na primer pri resonanci (17). Resonančne parametre, zlasti pole v kompleksni energijski ravnini, včasih boljše določimo z izračunom časovnega zamika kot z obliko resonančne krivulje. Prijetno nas je vzpodbudilo, da lahko dandanes s kromodinamiko na mreˇzi ˇze računamo fazne premike za sipanje piona na mezonih, celo v območju resonanc. Posebno pozornost smo namenili novim mezonskim resonancam. Naš eksperimentalni sodelavec v laboratoriju Belle je poročal o rezultatih, ki zadevajo domnevna vzbujena stanja čarmonija, dimezonov in tetrakvarkov. Slišali pa smo tudi napoved, da so nekatera visoka stanja mezonov D in B tetrakvarki ter predloge za eksperimente, s katerimi bi lahko te trditve preverili. Zanimiv je tudi napredek pri špekulacijah o hadronskih molekulah DN in BN. Nove meritve z dvojno polarizacijo v laboratoriju Jefferson Lab so razjasnile nekatere značilnosti spinske strukture jeder 3 He ter resonančnih parametrov pri elektroprodukciji pionov na nukleonih. Opis spektrov barionov, njihove elektro-šibke strukture in razpadnih širin se je uspešno razširil na hiperone in čarobne barione. Napredek je opazen tudi pri razvrščanju visokih barionskih multipletov (N = 3) z razvojem po recipročnem številu barv in s simetrijo O(3) SU(4); pri obravnavanju pionskih in fotonskih reakcij s sklopljenimi kanali; pri sipanju superteˇzkega hadrona, ki je morda tudi kandidat za temno snov. Presenečenje predstavlja nedavno odkriti magnetar, ki je preteˇzak, da bi njegovo jedro pojasnili s kvarkovskim plinom oziroma plazmo. Zdi se, da so trikvarkovske gruče obstojne tudi pri petkratni jedrski gostoti in tudi velja kar jedrska enačba stanja. Problemov in presenečenj torej ne zmanjka, in tudi zaporedje majhnih korakov očitno tvori plodno pot! Upamo torej, da se bodo naše tradicionalne Blejske delavnice še nadaljevale.

11 BLED WORKSHOPS IN PHYSICS VOL. 13, NO. 1 p.1 Proceedings of the Mini-Workshop Hadronic Resonances Bled,Slovenia,July 1-8,1 The Road to Extraction of S-Matrix Poles from ExperimentalData Saša Ceci, Milorad Korolija, and Branimir Zauner Rudjer Bosković Institute, Bijenička 54, HR-1 Zagreb, Croatia Abstract. By separating data points close to a resonance into intervals, and fitting all possible intervals to a simple pole with constant coherently added background, we obtained a substantial number of convergent fits. After a chosen set of statistical constraints was imposed, we calculated the average of a resonance pole position from the statistically acceptable results.we usedthismethod to find polepositionsofzboson. Breit-Wigner (BW) parameters are often used for the description of unstable particles(see e.g., Review of Particle Physics[1]), although shortcomings of such choice have been pointed out on numerous occasions. For example, Sirlin showed that thebwparametersofthezbosonweregaugedependent[].toresolvethisissue he redefined BW parameters, but also suggested usage of the S-matrix poles as an alternative, since poles are fundamental properties of the S-matrix and therefore gauge independent by definition. In a somewhat different study, Höhler advocated using S-matrix poles for characterization of nucleon resonances[3] in order to reduce confusion that arises when different definitions of BW parameters are used[4]. However, loosely defined[5] BW parameters of mesons and baryons are still being extracted from experimental analyses, compared among themselves [1], and used as input to QCD-inspired quark models [6] and as experiment-totheory matching points for lattice QCD[7]. Our group has been very interested in reducing human and model dependence from resonance parameters extraction procedures (from scattering matrices). We developed the regularization method for pole extraction from S-matrix elements[8].itsmaindisadvantageisthatitneedsverydensedata,onethatisattainable only after an energy dependent partial-wave analysis. The other method was the K-matrix pole extraction method [9] which needed the whole unitary S- matrix to begin with, making it impossible to use on any single reaction. Both of those methods were purely mathematical, and the only assumption were that there is a pole in the complex energy plane of an S-matrix. We had no physical input into our procedures. Therefore, we proclaimed these procedures modelindependent. The only thing missing, was a method which could be applied directly to the experimental data, e.g., total cross sections. In this proceeding, we illustrate a method for model-independent extraction of S-matrix pole positions directly from the data. TalkdeliveredbyS. Ceci
12 Saša Ceci, Milorad Korolija, and Branimir Zauner Thefirststepindevisingamethodforextractionofthepoleparametersfrom the experimental data is to set up an appropriate parameterization. The parameterization presented here is based on the assumption that close to a resonance, the T matrix will be well described with a simple pole and a constant background. The similar assumption was used in Höhler s speed plot technique[3]. The speed plot is a method used for the pole parameter extraction from the known scattering amplitudes. It is based on calculating the first order energy derivative of the scattering amplitude, with the key assumption that the first derivative of the background is negligible. The T matrixwith asingle pole and constant backgroundtermis givenby T(W) = r p Γ p / M p W iγ p / +b p, (1) where W is center-of-mass energy, r b and b b are complex, while M p and Γ p are real numbers. Total cross section is then proportional to T /q, where q is the initial center-of-mass momentum. Equation (1), as well as other similar forms (see e.g. [1]), are standardly called Breit-Wigner parameterizations, which can be somewhat misleading since M p and Γ p are generally not Breit-Wigner, but pole parameters (hence the index p). The square of the T matrix defined in Eq. (1) is given by T(W) = T (W M z ) +Γz/4 (W M p ) +Γp/4, () where, for convenience, we simplified the numerator by combining the old parameters into three new real-valued ones: T, M z, and Γ z. Pole parameters M p andγ p areretainedinthe denominator. With such a simple parameterization, it is crucial to use only data points close to the resonance peak. To avoid picking and choosing the appropriate data points by ourselves, we analyzed the data from a wider range around the resonance peak, and fitted localy the parameterization() to each set of seven successive data points (seven data points is minimum for our five-parameter fit). Then we increased the number of data points in the sets to eight and fitted again. We continued increasing the number of data points in sets until we fitted the whole chosen range. Such procedure allowed different background term for each fit, which is much closer to reality than assuming a single constant background term forthewholechosendataset(seee.g.discussionontheproblemswithspeedplot in Ref. [8]). In the end, we imposed a series of statistical constraints to all fits to distinguish the good ones. The whole analysis was done in Wolfram Mathematica 8 using NonlinearModelFit routine [11]. Having defined the fitting strategy, we tested the method by applying it to the case of the Z boson. The data set we used is from the PDG compilation [1], and shown in Fig. 1. Extracted pole masses are shown in the same figure: filled histogram bins show pole masses from the good fits, while the empty histogram bins are stacked to the solid ones to show masses obtained in the discarded fits. Height of the pole-mass histogram in Fig. 1 is scaled for convenience. ExtractedS-matrixpole massandwidthof Zboson aregivenintable1.the pole masses are in excelent agreement, while the pole widths are reasonably close.

14 4 Saša Ceci, Milorad Korolija, and Branimir Zauner In conclusion, we have illustrated here a model-independent method for extraction of resonance pole parameters from total cross sections and partial waves. Very good estimates for Z boson pole position were obtained. We are today witnessing the dawn of ab-initio calculations in low-energy QCD. In order to compare theoretical predictions with experimentally determined resonance states, we need first to establish proper point of comparison. We hope that our method, once it becomes fully operational, will help connecting experiment and theory. References 1. J. Beringer et al.,(particle Data Group), Phys. Rev. D86, 11 (1). A.Sirlin,Phys.

15 BLED WORKSHOPS IN PHYSICS VOL. 13, NO. 1 p.5 Proceedings of the Mini-Workshop Hadronic Resonances Bled,Slovenia,July 1-8,1 Unified Model for Light- and Heavy-Flavor Baryon Resonances JosephP. Day a,w. Plessas a, andki-seok Choi b a TheoreticalPhysics,Institute ofphysics,universityofgraz, Universitätsplatz5, A-81 Graz, Austria b Departmentof Physics,SoongsilUniversity,Seoul , Republic ofkorea Abstract. We report on the construction of a relativistic constituent-quark model capable of describing the spectroscopyof baryons with all flavors u, d, s, c, and b. Some selective spectra are presented, where comparisons to experimental data are yet possible. 1 Introduction Over the decades the constituent-quark model (CQM) has ripened into a stage where its formulation and solution are well based on a relativistic (i.e. Poincaréinvariant) quantum theory (for a thorough review of relativistic Hamiltonian dynamics see ref. [1]). In such an approach one relies on an invariant mass operator ^M, where the interactions are introduced according the so-called Bakamjian- Thomas construction []. If the conditions of the Poincaré algebra are fulfilled by ^M, this leads to relativistically invariant mass spectra. Relativistic constituent-quark models (RCQM) have been developed by several groups, however, with limited domains of validity. Of course, it is desirable to have a framework as universal as possible for the description of all kinds of hadron processes in the low- and intermediate-energy regions. This is especially true inviewof theadventofevermoredataonheavy-baryonspectroscopy from present and future experimental facilities. We have developed a RCQM that comprises all known baryons with flavors u,d,s,c,andbwithinasingle framework[3].therehavebeenonly afewefforts so far to extend a CQM from light- to heavy-flavor baryons. We may mention, for example, the approach by the Bonn group who have developed a RCQM, based on the t Hooft instanton interaction, along a microscopic theory solving the Salpeter equation [4] and extended their model to charmed baryons [5], still not yet covering bottom baryons. A further quark-model attempt has been undertakenbythemons-liègegrouprelyingonthelarge-n c expansion[6,7],partially extended to heavy-flavor baryons [8]. Similarly, efforts are invested to expand other approaches to heavy baryons, such as the employment of Dyson-Schwinger equations together with either quark-diquark or three-quark calculations [9, 1]. TalkdeliveredbyJ.P. Day
16 6 J.P. Day,W. Plessas,Ki-SeokChoi Also an increased amount of more refined lattice-qcd results has by now become availableonheavy-baryonspectra(see,e.g.,therecentworkbyliuetal.[11]and references cited therein). The Model Our RCQM is basedonthe invariant mass operator ^M = ^M free + ^M int, (1) where the free part corresponds to the total kinetic energy of the three-quark system and the interaction part contains the dynamics of the constituent quarks Q. In the rest frame of the baryon, where its three-momentum P = 3 i k i =, we may expresstheterms as ^M int = ^M free = 3 i=1 3 ^V ij = i<j ^m i + ^k i, () 3 i<j (^V conf ij + ^V hf ij). (3) Here,the^k i correspondtothethree-momentumoperatorsoftheindividualquarks with rest masses m i and the Q-Q potentials ^V ij are composed of confinement and hyperfine interactions. By employing such a mass operator ^M = ^P µ^p µ, with baryon four-momentum ^P µ = (^H,^P 1,^P,^P 3 ), the Poincaré algebra involving all ten generators {^H,^P i,^j i, ^K i }, (i = 1,,3), or equivalently {^P µ,^j µν }, (µ,ν =,1,,3),oftimeandspacetranslations,spatialrotationsaswellasLorentzboosts, can be guaranteed. The solution of the eigenvalue problem of the mass operator ^M yields the relativistically invariant mass spectra as well as the baryon eigenstates (the latter, of course, initially in the standard rest frame). We adoptthe confinement depending linearly onthe Q-Qdistancer ij V conf ij (r ij ) = V +Cr ij (4) withthestrengthc =.33fm,correspondingtothestringtensionofQCD.The parameterv = 4 MeVis only necessary to set the ground state of the whole baryon spectrum, i.e., the proton mass; it is irrelevant for level spacings. The hyperfine interaction is most essential to describe all of the baryon excitation spectra. In a unified model the hyperfine potential must be explicitly flavor-dependent. Otherwise, e.g., the N and Λ spectra with their distinct level orderings could not be reproduced simultaneously. Therefore we have advocated for the hyperfine interactionofour universal RCQM the SU(5) F GBEpotential [ 4 ] V hf (r ij ) = V 4 (r ij ) λ a iλ a j +V (r ij )λ iλ j σ i σ j. (5) a=1
17 Unified Model for Light- and Heavy-Flavor Baryon Resonances 7 Here, we take into account only its spin-spin component, which produces the most important hyperfine forces for the baryon spectra; the other possible force components together play only a minor role for the excitation energies[16]. While σ i represent the Pauli spin matrices of SU() S, the λ a i are the generalized Gell- Mann flavor matrices of SU(5) F for quark i. In addition to the exchange of the pseudoscalar 4-plet also the flavor-singlet is included because of the U(1) anomaly. The radial form of the GBE potential resembles the one of the pseudoscalar meson exchange V β (r ij ) = g β 4π 1 1m i m j [ µ e µ βr ij ] β 4πδ(r ij ) r ij for β = 4 and β =.

The present universal GBE RCQM produces the spectra in the light and strange sectors with similar or even better quality than the previous GBE RCQM [13]. In Figs. 1 and we show the ground states and the first two excitations of SU(3) F singlet, octet, and decuplet baryons up to J = 7, for which experimental data of at least three stars are quoted by the PDG [15]andJ P is known. Evidently a good overall description is achieved. Most importantly, the right level orderings specifically in the N,, and Λ spectra as well as all other SU(3) F ground and excited states are reproduced in accordance with phenomenology. The reasons are exactly the same as for the previous GBE RCQM, what has already been extensively discussed in the literature [1 14]. Unfortunately, the case of the Λ(145) excitation could still not be resolved. It remains as an intriguing problem that can possibly not be solved by RCQMs relying on {QQQ} configurations only; an explicit coupling to the K-N decay channel whose threshold lies nearby might be needed.

Of course, the presently available data base on charm and bottom baryon states is not yet very rich and thus not particularly selective for tests of effective Q-Q hyperfine forces. The situation will certainly improve with the advent of further data from ongoing and planned experiments. Beyond the comparison to experimental data, we note that the theoretical spectra produced by our present GBE RCQM are also in good agreement with existing lattice-qcd results for heavy-flavor baryons. This is especially true for the charm baryons vis-à-vis the recentwork by Liu etal.[11].
21 Unified Model for Light- and Heavy-Flavor Baryon Resonances 11 4 Discussion and Conclusion We emphasize that the most important ingredients into the present RCQM are relativity, specifically Poincaré invariance, and a hyperfine interaction that is derived from an interaction Lagrangian built from effective fermion (constituent quark) and boson (Goldstone boson) fields connected by a pseudoscalar coupling [1]. It appears that such kind of dynamics is quite appropriate for constituent quarks of any flavor. AsaresultwehavedemonstratedbytheproposedGBERCQMthatauniversal descriptionof all known baryons is possible in asingle model.here,we have considered only the baryon masses (eigenvalues of the invariant mass operator ^M). Beyond spectroscopy the present model will be subject to further tests with regard to the baryon eigenstates, which are simultaneously obtained from the solution of the eigenvalue problem of ^M. They must prove reasonable in order to make the model a useful tool for the treatment of all kinds of baryons reactions within a universal framework. 5 Acknowledgement This work was supported by the Austrian Science Fund, FWF, through the Doctoral Program on Hadrons in Vacuum, Nuclei, and Stars(FWF DK W13-N16).
