Abstract:

We present preliminary results for meson spectral functions at nonzero momentum, obtained from quenched lattice QCD simulations at finite temperature using the Maximal Entropy Method. Twisted boundary conditions are used to have access to many momenta p~T. For light quarks, we observe a drastic modification when heating the system from below to above Tc. In particular, for the vector spectral density we find a nonzero spectral weight at all energies.
