TL;DR

This paper investigates how gluon damping in hot QCD matter affects heavy-quark energy loss, showing that damping significantly alters quenching at high transverse momenta in a Monte Carlo simulation.

Contribution

It introduces a Monte Carlo approach to incorporate gluon damping effects into heavy-quark in-medium propagation models, highlighting their impact on quenching.

Findings

Heavy-quark quenching is significantly affected at high transverse momenta.

Gluon damping must be considered for accurate heavy-quark energy loss modeling.

Abstract

In this conference contribution, we discuss the influence of gluon-bremsstrahlung damping in hot, absorptive QCD matter on the heavy-quark radiation spectra. Within our Monte-Carlo implementation for the description of the heavy-quark in-medium propagation we demonstrate that as a consequence of gluon damping the quenching of heavy quarks becomes significantly affected at higher transverse momenta.
