Description

We study, in a pQCD calculation augmented by nuclear effects, the jet energy loss needed to reproduce the π0 spectra in Au+Au collisions at large pT, measured by PHENIX at RHIC. The transverse width of the parton momentum distributions (intrinsic kT) is used phenomenologically to obtain a reliable baseline pp result. Jet quenching is applied to the nuclear spectra (including shadowing and multiscattering) to fit the data. Latest results on fluctuating gluon radiation are considered to measure the opacity of the produced hot dense matter at RHIC energy. (orig.)
