Abstract
We studied the meson properties at finite temperature using quenched lattice QCD simulations with two-flavor truncated overlap fermions.
We calculated the screening masses of four types of meson, pseudo-scalar, vector, scalar and axial-vector mesons.
We observed a tendency for the screening masses in all the channels to be degenerate at high temperature,
which is in accord with the effective restoration of the $U_A(1)$ symmetry.
