Competition of Heavy Quark Radiative and Collisional Energy Loss in Deconfined Matter

TL;DR

This paper extends a model of heavy quark energy loss in quark-gluon plasma by including radiative effects, analyzing their competition and impact on experimental observables.

Contribution

It introduces a combined model of collisional and radiative energy loss for heavy quarks in QGP, providing preliminary results and discussing their experimental implications.

Findings

Current data cannot distinguish between collisional and radiative energy loss mechanisms.

Radiative energy loss inclusion affects the interpretation of nuclear modification factors.

The model advances understanding of heavy quark energy loss in deconfined matter.

Abstract

We extend our recently advanced model on collisional energy loss of heavy quarks in a quark gluon plasma (QGP) by including radiative energy loss. We discuss the approach and present first preliminary results. We show that present data on nuclear modification factor of non photonic single electrons hardly permit to distinguish between those 2 energy loss mechanisms.
