Identified Particle Spectra and Jet Interactions with the Medium
  Through a combination of detector upgrades and advancements in analysis techniques, physicist at RHIC are extending their ability to identify particles at high pT . With these new capabilities some outstanding questions are being addressed: particularly regarding baryon production. Here I present an overview of new data on identified particle elliptic flow (v2), identified particle pT spectra and identified hadron-hadron correlations. The observed phenomena provide insights into hard parton interactions with the bulk matter created in heavy-ion collisions and the relevant degrees-of-freedom during its early stages.
