Dynamic scaling and quenching for heavy quark in the linear expanding medium

TL;DR

This paper demonstrates that in a linear expanding quark-gluon plasma, the energy loss of heavy quarks can be approximated by scaling, and the effective quenching parameter is independent of quark mass.

Contribution

It introduces the approximation of scaling for heavy quark energy loss in expanding QGP and shows the quenching parameter's independence from quark mass.

Findings

Scaling is a good approximation for heavy quark energy loss.

The effective quenching parameter does not depend on quark mass.

Applicable to linear expanding quark-gluon plasma.

Abstract

We show that scaling is a good approximation for the energy loss of the heavy quark propagating through linear expanding quark-gluon plasma (QGP), the effective quenching parameter does not depend on quark mass.
