Jet Quenching and Photon Productions in Thermal QCD
Sangyong Jeon (McGill University)

Abstract: So far several jet quenching scenarios have been proposed that can explain the current RHIC nuclear modification factor equally well. Among them, the AMY approach taken by Turbide, Gale, Jeon and Moore is the only one that takes into account full leading order thermal QCD effects. In this talk, I will summarize the strong points as well as the weak points of this approach and explain the way we calculated the RAA. I will also talk about photon (real and virtural) production rate which can be naturally incorporated in our calculation fully consistently to the leading order in &alphaEM and how it fares with the experimental results.
