Charmonium spectral functions at finite momenta in the gluon plasma from lattice QCD

This is the authors' abstract. We don't add key points for this paper.

We study the charmonium spectral function in the gluon plasma on 643 × Nτ quenched anisotropic lattices with anisotropy aσ/aτ = 4, analyzing correlation functions of charmonia by the maximum entropy method. We focus on finite momentum effects on the charmonium spectral function in order to understand the J/ψ suppression mechanism in relativistic heavy ion collisions from the first principles of QCD.
