Open-Flavor Heavy Hadron Production in Heavy-Ion Collisions

TL;DR

This paper models the production of open-flavor heavy hadrons in heavy-ion collisions using a quark coalescence approach, evaluating yields and momentum distributions for various hadrons including exotic states, considering chiral symmetry effects.

Contribution

It provides a unified framework for calculating production of conventional and exotic heavy hadrons in heavy-ion collisions with realistic wave functions.

Findings

Yields and transverse momentum distributions for heavy hadrons are computed.

Chiral symmetry restoration impacts hadron production.

Results include both conventional and exotic heavy hadrons.

Abstract

We study the production of open-flavor heavy hadrons in relativistic heavy-ion collisions. The hadronization in the quark-gluon plasma is described in the quark coalescence model. We evaluated yields and transverse momentum distributions. A simultaneous study of conventional and exotic hadrons is carried out. The Wigner functions are evaluated using hadron wave functions obtained from a single realistic quark model. Thus, results are presented in a single framework for the production of open-flavor heavy mesons, baryons, and exotic tetraquarks, in particular: $D^{0}$, $B^{0}$, $\Lambda_{Q}$, $\Sigma_{Q}$, $\Xi_{Q}$, $\Xi_{QQ^\prime}$, and $T_{QQ^\prime}$ ($Q,Q^\prime=c$ or $b$). The consequences of a partial restoration of chiral symmetry at the hadronization temperature are studied in detail.
