Spectra and elliptic flow of charmed hadrons in HYDJET++ model

TL;DR

This paper models the production and elliptic flow of prompt charmed mesons in PbPb collisions at 2.76 TeV using the HYDJET++ framework, combining thermal and pQCD mechanisms, and compares results with LHC data.

Contribution

It introduces a detailed simulation of charmed meson spectra and flow in heavy ion collisions using the HYDJET++ model, integrating thermal and pQCD production methods.

Findings

Model reproduces charmed meson spectra and flow consistent with LHC data.

Thermal and pQCD mechanisms effectively describe charm production.

Results support the use of HYDJET++ for heavy-flavor studies in heavy ion collisions.

Abstract

Heavy-flavour quarks are predominantly produced in hard scatterings on a short time-scale and traverse the medium interacting with its constituents, thus they are one of the effective probes of the transport properties of the medium formed in relativistic heavy ion collisions. On the other hand, the thermal production of heavy-flavour quarks in quark-gluon plasma (QGP) is itself of interest. In this report, the production and elliptic flow of the prompt charmed mesons $D^0$, $D^+$, $D^{*+}$ and $J/\psi$ in PbPb collisions at the center-of-mass energy 2.76 TeV per nucleon pair are described in the framework of two-component HYDJET++ model. The model combines thermal and pQCD production mechanisms. The spectra and elliptic flow of charmed mesons are presented, the results are compared with LHC data.
