Statistical hadronization of b-quarks in Pb-Pb collisions at LHC energy: a case for partial equilibration of b-quarks?

TL;DR

This paper uses the statistical hadronization model to predict bottomonium yields in Pb-Pb collisions at LHC, exploring the potential partial thermalization of b-quarks and providing new predictions for unmeasured open-beauty hadrons.

Contribution

It introduces a comprehensive prediction framework for bottomonia and open-beauty hadrons in heavy-ion collisions, highlighting the role of partial b-quark equilibration.

Findings

Predicted centrality dependence of $$ production.

Provided estimates for unmeasured open-beauty hadrons.

Supported the hypothesis of partial b-quark thermalization.

Abstract

Predictions are presented within the framework of the statistical hadronization model for integrated yields of bottomonia in Pb-Pb collisions at the LHC. We investigate the centrality dependence of $\Upsilon$ production and provide predictions for a large set of still-unmeasured open-beauty hadrons.
