Abstract
We study spatial isovector meson correlators in N-f = 2 QCD with dynamical domain-wall fermions on 32(3) x 8 lattices at temperatures T = 220-380 MeV. We measure the correlators of spin-one (J = 1) operators including vector, axial-vector, tensor and axial-tensor. Restoration of chiral U(1)(A) and SU(2)(L) x SU(2)(R) symmetries of QCD implies degeneracies in vector-axial-vector (SU(2)(L) x ...
We study spatial isovector meson correlators in N-f = 2 QCD with dynamical domain-wall fermions on 32(3) x 8 lattices at temperatures T = 220-380 MeV. We measure the correlators of spin-one (J = 1) operators including vector, axial-vector, tensor and axial-tensor. Restoration of chiral U(1)(A) and SU(2)(L) x SU(2)(R) symmetries of QCD implies degeneracies in vector-axial-vector (SU(2)(L) x SU(2)(R)) and tensor-axial-tensor (U(1)(A)) pairs, which are indeed observed at temperatures above T-c. Moreover, we observe an approximate degeneracy of all J = 1 correlators with increasing temperature. This approximate degeneracy suggests emergent SU(2)(CS) and SU(4) symmetries at high temperatures, that mix left- and right-handed quarks.
