Description
The fate of the charmonia as well as the charm quark diffusion coefficients at nonzero temperature are important to understand the observed nuclear modification factors of charmonia as well as open charm mesons in heavy ion collision experiments.
In this talk, we will present our recent results on charmonia spectral functions obtained from quenched lattice QCD simulations at $T\in [0.35,2.25]T_c$. The simulations have been performed on very large and fine lattices where charm quarks can be treated relativistically. We will start by showing the temperature dependence of charmonia correlation functions at several temperatures above and below the deconfinement temperature. We will then discuss the temperature dependences of spectral functions and the resulting charm quark diffusion coefficients obtained from the Maximum Entropy Method. Finally we will present the results on the screening masses of charmonia as well as the dispersion relation at nonzero momenta.
