Screening Effects on the Binding Energy and Stability of Quarkonia States

TL;DR

This paper investigates how color and vacuum screening at finite temperatures influence the binding energy and stability of quarkonia states, providing insights into their thermal behavior in a quark-gluon plasma.

Contribution

It introduces a temperature-dependent potential model to analyze medium effects on charmonia and bottomonia, comparing color and vacuum screening impacts on quarkonia stability.

Findings

Color screening reduces quarkonia binding at high temperatures.

Vacuum screening effects are significant at lower temperatures.

The model predicts dissociation temperatures for different quarkonia states.

Abstract

We have studied the thermal stability of Quarkonia states by computing the effects of color-screening and vacuum screening based on a temperature dependent screened coulomb plus power potential for the quark-antiquark interaction. Medium effects on the properties of charmonia and bottomonia states are studied. The color screening and the vacuum screening effects on the stability of the quarkonia states are also separately calculated for comparison.
