# Jets in non-equilibrium quark-gluon plasma

## TL;DR

This paper investigates how jets interact with a non-equilibrium quark-gluon plasma, focusing on gluon emission and the effects of chromomagnetic instabilities on jet particle deflection.

## Contribution

It provides a quantum field theoretical framework for understanding jet behavior in unstable, out-of-equilibrium QGP, accounting for Weibel instabilities.

## Key findings

- Chromomagnetic fields cause jet particle deflection.
- Out-of-equilibrium medium enhances gluon emission rates.
- Weibel instabilities lead to exponential growth of chromomagnetic fields.

## Abstract

Jets are a promising way to probe the non-equilibrium physics of quark-gluon plasma (QGP). We study how an out-of-equilibrium medium induces a jet particle to emit gluons. Evaluation of the emission rate is complicated by Weibel instabilities which lead to an exponential growth of chromomagnetic fields. Deriving a quantum field theoretical description of an unstable QGP medium, we show that the chromomagnetic fields deflect jet particles during the gluon emission.
