Potential alteration of the bottomonium states in XeXe collisions

Abstract

Researchers have investigated the suppression and survival of bottomonium in relativistic Heavy-Ion Collisions (HIC) to understand Quark-Gluon Plasma (QGP) characteristics better. The interplay between dissociation and recombination in QGP is typically explored using the Boltzmann transport equation, with a particular focus on the dissociation rates of newly formed bound states. This study considers the cumulative effects of gluon-induced dissociation, colour screening and recombination on bottomonium production in HIC. The model uses parameters of Xenon-Xenon (XeXe) collisions at \(\sqrt{s_{\text {NN}}} = 5.44\) TeV from the Large Hadron Collider (LHC). By employing the Bateman solution method to calculate recombination rates, this research provides a detailed analysis of the recombination and dissociation dynamics of the QGP and how they impact the bottomonium states in medium-sized collision systems like XeXe. The model successfully explains the observed suppression of \(\Upsilon (nS)\) states in such a system.
