Lattice study of meson properties at fine temperature using the truncated overlap fermions
January 03, 2020
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.
