    Abstract

    We compute correlators and spectral functions for J/ and c mesons at nonzero momentum on anisotropic lattices with Nf = 2. We find no evidence of significant momentum dependence at the current level of precision. In the pseudoscalar channel, the ground state appears to survive up to T 450MeV or 2.1Tc. In the vector channel, medium modifications may occur at lower temperatures.
