Upsilon suppression at energies available at the BNL Relativistic Heavy Ion Collider and at the CERN Large Hadron Collider in a modified color screening scenario

TL;DR

This paper extends a modified color screening model to analyze Upsilon suppression in quark-gluon plasma at RHIC and LHC energies, comparing theoretical predictions with experimental data to understand quarkonium behavior in heavy ion collisions.

Contribution

It introduces an extension of a previous model to specifically predict Upsilon suppression patterns in QGP at different energies and centralities.

Findings

Suppression patterns vary with collision energy and centrality.

Model predictions align with experimental data for Upsilon states.

Provides insights into QGP properties through bottomonium suppression.

Abstract

The suppression of heavy quarkonia e.g. $J/\psi$, $\Upsilon$ etc. is considered as a suitable probe to identify the nature of the matter created in heavy ion collisions. Recently we have presented a modified colour screening model for $J/\psi$ suppression in the quark gluon plasma (QGP) using quasiparticle model as the equation of state. In this paper, we extend our model to calculate the anomalous suppression of various states of $\Upsilon$ arising due to QGP medium alone. We obtain the suppression patterns of different bottomonia states with respect to centrality at various available collision energies and compare them with the available experimental data.
