Jets and flow within a pQCD-based partonic transport model

TL;DR

This paper uses the BAMPS model to simulate jet quenching and elliptic flow in heavy ion collisions at RHIC, incorporating elastic and inelastic processes, and explores energy loss mechanisms for gluons and quarks.

Contribution

It introduces a dynamic pQCD-based transport model that includes elastic and inelastic processes, and investigates energy loss differences between gluons and quarks.

Findings

Inelastic processes show weaker color factor dependence than expected.

Self-quenching effects influence energy loss in the model.

Preliminary extension to include light quarks is discussed.

Abstract

We present fully dynamic simulations of heavy ion collisions at RHIC energies within the perturbative QCD-based partonic transport model BAMPS, focusing on the simultaneous investigation of jet-quenching and elliptic flow. The model consistently features elastic and inelastic 2 -> 3 processes, the latter being based on the Gunion-Bertsch matrix element. We discuss first attempts to extend the model to include light quark degrees of freedom and study the energy loss of high energy gluons and quarks in a static partonic medium. The difference between gluons and quarks in inelastic processes is found to be weaker than expected from color factors, due to a self-quenching effect associated with a cut-off modeling the LPM effect.
