Ja n 19 96 LBL - 37688 Thermal Equilibration in an Expanding Parton Plasma
Thermalization in an expanding parton plasma is studied within the framework of Boltzmann equation in the absence of any mean fields. In particular, we study the time-dependence of the relaxation time to the lowest order in finite temperature QCD and how such time-dependence affects the thermaliza-tion of an expanding parton plasma. Because of Debye screening and Landau damping at finite temper...
متن کاملApproach to Parton Equilibration *
Perturbative QCD-based models of parton production and equilibration in ultrarela-tivistic heavy ion collisions are reviewed with an emphasis on the treatment of quantum interference effects. Uncertainties in the initial parton production and their effects on later parton equilibration are considered. Probes of early parton dynamics are also discussed.
متن کاملParton Equilibration in Ultrarelativistic Heavy Ion Collisions
Medium effects which include color screening and Landau-Pomeranchuk-Migdal suppression of induced radiation are discussed in connection with the equilibration of dense partonic system in ultrarelativistic heavy ion collisions. Taking into account of these medium effects, the equilibration rate for a gluonic gas are derived and the consequences are discussed.
متن کاملEffect of baryon density on parton production, chemical equilibration and thermal photon emission from quark gluon plasma
The effect of baryon density on parton production processes of gg ⇀↽ ggg and gg ⇀↽ qq̄ is studied using full phase space distribution function and also with inclusion of quantum statistics i.e. Pauli blocking and Bose enhancement factors, in the case of both saturated and unsaturated quark gluon plasma. The rate for the process gg ⇀↽ qq̄ is found to be much less as compared to the most commonly u...
متن کاملParton energy loss in an expanding quark-gluon plasma: Radiative vs collisional
We perform a comparison of the radiative and collisional parton energy losses in an expanding quark-gluon plasma. The radiative energy loss is calculated within the light-cone path integral approach [4]. The collisional energy loss is calculated using the Bjorken method with an accurate treatment of the binary collision kinematics. Our numerical results demonstrate that for RHIC and LHC conditi...
