Parallel Talk QCD at high temperature QCD at high temperature


Christian Rohrhofer (Karl-Franzens Universität Graz)


We study spatial isovector meson correlators in $n_f=2$ QCD with dynamical domain-wall fermions on $32^3\times 8$ lattices at temperatures $T=220-380$ MeV. We measure the correlators of all spin-one ($J=1$) isovector operators. We observe an approximate degeneracy of all considered correlators with increasing temperature. This approximate degeneracy suggests emergent $SU(2)_{CS}$ and $SU(2*n_f)$ symmetries at high temperatures, that mix left- and right-handed quarks.
