  We investigate mesonic screening correlators at T=2T_c using the overlap
Fermions in the quenched approximation, where T_c 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 rho and pi 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.
