Abstract

Based on simulations of 2+1 flavor lattice QCD with Möbius domain wall fermions at high temperatures, we compute a series of spatial correlation functions to study the screening masses in mesonic states. We compare these masses with the symmetry relations for various quark masses and lattice sizes at temperatures above the critical point. Using these spatial correlation functions we examine the SU(2)_L × SU(2)_R symmetry as well as the anomalously broken axial U(1)_A symmetry. Additionally we explore a possible and emergent chiral-spin symmetry SU(2)_CS.
