Description
In this study, we investigate the effective restoration of axial U(1) symmetry by calculating the scalar and pseudo-scalar meson screening masses using Möbius domain wall fermions with physical quark masses. Unlike the widely used staggered fermions, which suffer from taste violations that lead to unphysical behavior-such as scalar screening masses failing to reach their physical values at low temperatures-Möbius domain wall fermions preserve near-exact chiral symmetry. We compare our results with those obtained using staggered fermions to offer new insights into the role of axial U(1) symmetry in the QCD phase transition.
