Charmonium properties in the quark-gluon plasma

TL;DR

This study investigates how different charmonium states behave in quark-gluon plasma, showing S-wave states survive at high temperatures while P-waves dissolve earlier, providing insights into quarkonium suppression.

Contribution

First lattice QCD analysis of charmonium correlators and spectral functions in 2-flavour QCD on anisotropic lattices at finite temperature.

Findings

S-wave charmonium states survive near 2T_c

P-wave states melt below 1.2T_c

Provides temperature-dependent spectral function data

Abstract

We present results for charmonium correlators and spectral functions in 2-flavour CD on anisotropic lattices. Our results indicate that the S-waves (J/psi and eta_c) survive up to temperatures close to 2T_c, while the P-waves (chi_c0 and chi_c1) melt away below 1.2T_c.
