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.
Spectral functions provide insight into the real-time dynamics of the quark-gluon plasma.
In the context of heavy-ion collisions and RHIC, lattice QCD studies carried out so far
address, among others, the survival of charmonium up to T 1.6Tc [14], the rate of
dilepton production [5], and transport coefficients [610]. Recently, analytical studies of
