Charmonium near the deconfining transition on the lattice

Abstract

We study the charmonium properties at finite temperature using quenched lattice QCD simulations. Although a simple potential model analysis indicates no bound state at $T>1.05T_c$, our analyses of the spatial correlation between quark and anti-quark and the spectral function indicate that a bound-state-like structure may survive even above $T_c$.
