Wakes in a Collisional Quark-Gluon Plasma

TL;DR

This paper investigates how collisions in a quark-gluon plasma affect the wake structures created by a moving parton, using a transport model that incorporates collisions, revealing significant differences from collisionless scenarios.

Contribution

It introduces a transport theoretical approach with collisions to study wakes in a quark-gluon plasma, extending previous collisionless models.

Findings

Collision effects significantly alter wake structures.

The transport model with collisions shows different wake patterns.

Results highlight the importance of including collisions in plasma wake studies.

Abstract

Wakes created by a parton moving through a static and infinitely extended quark-gluon plasma are considered. In contrast to former investigations collisions within the quark-gluon plasma are taken into account using a transport theoretical approach (Boltzmann equation) with a Bhatnagar-Gross-Krook collision term. Within this model it is shown that the wake structure changes significantly compared to the collisionless case.
