Testing the mechanism of QGP-induced energy loss
Ivan Vitev
Abstract
We present an analytic model of jet quenching, based on the (D)GLV energy loss formalism, to describe the system size dependence of QGP-induced parton absorption in relativistic heavy ion collisions. Numerical simulations of the transverse momentum dependence of jet quenching are given for central Au+Au and Cu+Cu reactions. Low pT dijet correlations are shown to be sensitive to the reappearance of the lost energy as soft hadrons. At high pT we find that the attenuation of dihadrons is similar to that of single inclusive particles. Comparison to recent data from PHENIX and STAR is given as test of the jet quenching theory.
