Description
An updated version of the partonic transport model Boltzmann Approach to
MultiParton Scatterings (BAMPS) is presented, which allows interactions
among all partons: gluons, light quarks, and heavy quarks with elastic
and inelastic collisions. We introduce the improved Gunion-Bertsch
matrix element, which cures problems of the original Gunion-Bertsch
result in characteristic regions of the phase space. Verified by
extensive numerical calculations, the improved matrix element agrees
well with the exact calculation. With the new matrix element, important
properties of the quark-gluon-plasma in heavy-ion collisions such as the
thermalization time of the plasma and the shear viscosity over entropy
density ratio are calculated within the microscopic transport model
BAMPS. Furthermore, we compare our results of the nuclear modification
factor and elliptic flow to experimental data at RHIC and LHC.
