QGP collective effects and jet transport

TL;DR

This paper uses numerical simulations to study how jets interact with quark-gluon plasma, revealing anisotropic broadening effects due to plasma instabilities in heavy-ion collisions.

Contribution

It introduces a novel simulation approach combining Boltzmann-Vlasov dynamics with classical Yang-Mills fields to analyze jet-plasma interactions.

Findings

Jet broadening is stronger along the beam line than azimuthally.

The coupling of jets to the plasma is estimated independently of infrared cutoffs.

Field configurations with B_t > E_t and E_z > B_z are generated via plasma instabilities.

Abstract

We present numerical simulations of the SU(2) Boltzmann-Vlasov equation including both hard elastic particle collisions and soft interactions mediated by classical Yang-Mills fields. We provide an estimate of the coupling of jets to a hot isotropic plasma, which is independent of infrared cutoffs. In addition, we investigate jet propagation in anisotropic plasmas, as created in heavy-ion collisions. The broadening of jets is found to be stronger along the beam line than in azimuth due to the creation of field configurations with B_t>E_t and E_z>B_z via plasma instabilities.
