Simulation of Jet Quenching in Heavy Ion Collisions

Abstract

One of the important tools for studying the properties of quark-gluon plasma (QGP) in ultrarelativistic heavy ion collisions is the analysis of a QCD jet production. The medium-induced energy loss of energetic partons, “jet quenching”, should be very different in the cold nuclear matter and QGP, resulting in many observable phenomena . Recent RHIC data on high-pT particle production at √ s = 200 A GeV are in agreement with the jet quenching hypothesis (see, e.g., 2 and references therein). At LHC, a new regime of heavy ion physics will be reached at √ sNN = 5.5A TeV where hard and semi-hard particle production can stand out against the underlying soft events. The initial gluon densities in Pb+Pb reactions at LHC are expected to be much higher than those at RHIC, implying a stronger partonic energy loss, observable in new channels. In the most of available Monte-Carlo heavy ion event generators the mediuminduced partonic rescattering and energy loss are either ignored or implemented insufficiently. Thus, in order to analyze RHIC data on high-pT hadron production and test the sensitivity of LHC observables to the QGP formation, the development of adequate and fast Monte-Carlo tool to simulate the jet quenching is necessary. 2.
