Synchrotron-like gluon emission in the quark-gluon plasma

TL;DR

This paper develops a quasiclassical theory for synchrotron-like gluon emission in quark-gluon plasma, highlighting its potential role in jet quenching and contrasting it with previous models.

Contribution

It introduces a new quasiclassical approach to gluon emission in plasma and discusses the impact of plasma instabilities on jet quenching phenomena.

Findings

Synchrotron emission can significantly influence jet quenching.

The gluon spectrum differs from previous Schwinger proper time method results.

Plasma instabilities may generate strong chromomagnetic fields affecting gluon emission.

Abstract

A quasiclassical theory of the synchrotron-like gluon emission is discussed. We show that the synchrotron emission may be important in the jet quenching if the plasma instabilities generate a chromomagnetic field about $m^{2}_{D}/g$. Our gluon spectrum disagrees with that obtained by Shuryak and Zahed within Schwinger's proper time method.
