[Physics] How many times have we found the Higgs-Boson?

Okay, as much as my knowledge goes, we have only found the Higgs-Boson at CERN and also that the ratio of number of positive experiments vs negative experiments is really poor. That is, number of failed experiment >> number of successful experiments.

Now, I could be wrong. But I would stand by that I am not. So in this case, we are completely going against the scientific method. Higgs-Boson is yet to found in a lab other than CERN and we hardly seem to find it even after having found it already once. 

How come the scientific community accepts this? You would say that CERN has reputation, I would say that this is a bias and science requires that other labs/teams get the same result. We should atleast get the number of successful experiments higher than the failed ones.

You have any thoughts?

The first thing to understand is that the existence of the Higgs boson isn't one monolithic hypothesis, because it would be far too difficult to falsify if it were. Instead, it's typically treated as an array of hypotheses of the form "The Higgs boson exists and has mass 120 GeV," "The Higgs boson exists and has mass 121 GeV," etc. Each of these hypotheses can be falsified independently, and that's exactly what previous experiments have done. They haven't concluded that the Higgs didn't exist, only that it didn't exist at the masses that they were able to test. The experiments at the LHC were the first ones that tested the hypothesis "The Higgs exists and has mass 125 GeV," and they confirmed that it was true.

The second thing is that the LHC isn't one experiment. It's an accelerator set up to allow for experimentation, but there are multiple experiments along the beam path which operate independently. The two largest are ATLAS (**A** **T**oroidal **L**HC **A**pparatu**s**) and CMS (Compact Muon Solenoid), and they both found the Higgs around the same time. Thus, the number of positive results for this particular hypothesis is two, while the number of negative results is zero.

Finally, you might rightfully be concerned that a single experiment investigating so many independent hypotheses simultaneously is bound to return a positive result on *some* of them purely statistically. However, this has been accounted for, and is the reason that the significance threshold in experimental particle physics is so high, "five sigmas" to confirm the existence of a new particle. "Five sigmas" means that the result has to be five standard deviations from the value predicted by the null hypothesis. The probably of getting that result as a statistical anomaly (for one experiment) is about 3x10^(-7).
