Abstract

We investigate mesonic screening correlators at T=2Tc using the overlap fermions in the quenched approximation, where Tc is the QCD phase transition temperature. Using lattices with temporal extent up to 8 we found that both pseudoscalar and vector correlators exhibit a nice cosh behaviour, leading to a plateau behaviour in the local screening masses as a function of distance. The ρ and π masses so determined show very little variation with the lattice spacing a. This augurs well for the use of chiral fermions, and further suggests the small deviations of these masses from the ideal gas values are genuine effects of interactions.
