Charmonium in finite temperature lattice QCD

TL;DR

This paper investigates the behavior of charmonium states, like J/ψ mesons, near the deconfining transition in finite temperature lattice QCD, analyzing correlators and wave functions to understand bound state survival.

Contribution

It provides a comparative analysis of meson correlators above and below the critical temperature, offering insights into the existence of c-cbar bound states at finite temperature.

Findings

Charmonium correlators change across the transition.

Wave function analysis suggests possible bound state persistence.

Results contribute to understanding quarkonium behavior in quark-gluon plasma.

Abstract

We study hadron properties near the deconfining transition in the finite temperature lattice QCD. This paper focus on the heavy quarkonium states, such as $J/\psi$ meson. We compare the meson correlators above and below $T_c$ and discuss the possibility of the $c\bar{c}$ bound state by observing the wave function.
