On Melting Temperature of Heavy Quarkonium with the AdS/CFT Implied Potential

TL;DR

This paper investigates the melting temperatures of heavy quarkonium states in a quark-gluon plasma using potentials derived from AdS/CFT duality, comparing different metrics and aligning results with lattice data.

Contribution

It introduces a method to estimate quarkonium dissociation temperatures using AdS/CFT-implied potentials and compares different holographic models.

Findings

Dissociation temperatures for J/ψ and Υ agree with lattice results within a factor of two.

Both vanilla AdS-Schwarzschild and IR cutoff models are effective in this analysis.

The approach provides a holographic perspective on quarkonium melting in QGP.

Abstract

The quarkonium states in a quark-gluon plasma is examined with the potential implied by AdS/CFT duality. Both the vanila AdS-Schwarzschild metric and the one with an infrared cutoff are considered. The calculated dissociation temperatures for $J/\psi$ and $\Upsilon$ are found to agree with the lattice results within a factor of two.
