摘要：

We study the charmonium spectral function in the gluon plasma on 64(3) x N-tau quenched anisotropic lattices with anisotropy a(sigma)/a(tau) = 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/psi suppression mechanism in relativistic heavy ion collisions from the first principles of QCD.
