Charmonium and bottomonium spectral functions in the vector channel

Abstract

In this paper we report our results on quarkonium spectral functions in the\nvector channel obtained from quenched lattice QCD simulations at $T\\in[0.75,\n2.25]~T_c$. The calculations have been performed on very large and fine\nisotropic lattices where both charm and bottom quarks can be treated\nrelativistically. The spectral functions are reconstructed using the Maximum\nEntropy Method. We study the dissociation of quarkonium states from the\ntemperature dependence of the spectral functions and estimate heavy quark\ndiffusion coefficients using the low-frequency behavior of the vector spectral\nfunctions.\n
