Chiral-spin symmetry of the meson spectral function above Tc
Recently, via calculation of spatial correlators of J=0,1 isovector operators using a chirally symmetric Dirac operator within NF=2 QCD, it has been found that QCD at temperatures Tc−3Tc is approximately SU(2)CS and SU(4) symmetric. The latter symmetry suggests that the physical degrees of freedom a...
