Momentum distribution of charm hadrons in a fluid-dynamic approach

TL;DR

This paper demonstrates a fluid-dynamic approach to modeling charm quark diffusion in the QCD plasma, providing spectra predictions that are compared with experimental data to constrain the plasma's transport properties.

Contribution

It introduces a novel fluid-dynamic framework for describing charm quark diffusion in the QGP, bridging transport theory and fluid dynamics.

Findings

Fluid-dynamic model successfully reproduces charm hadron spectra.

Comparison with experimental data constrains QGP transport coefficients.

The approach offers a new tool for studying heavy-quark dynamics in QGP.

Abstract

Exploiting a mapping between transport theory and fluid dynamics, we show how a fluid-dynamic description of the diffusion of charm quarks in the QCD plasma is feasible. We show results for spectra of charmed hadrons obtained with a fluid-dynamic description of the quark-gluon plasma (QGP) coupled with the conservation of a heavy-quark - antiquark current. We compare our calculations with the most recent experimental data in order to provide further constraints on the transport coefficients of the QGP.
