Query: Meson correlation functions at high temperature QCD: $SU(2)_{CS}$
  symmetry vs. free quarks   We report on the progress of understanding spatial correlation functions in
high temperature QCD. We study isovector meson operators in $N_f=2$ QCD using
domain-wall fermions on lattices of $N_s=32$ and different quark masses. It has
previously been found that at $\sim 2T_c$ these observables are not only
chirally symmetric but in addition approximately $SU(2)_{CS}$ and $SU(4)$
symmetric. In this study we increase the temperature up to $5T_c$ and can
identify convergence towards an asymptotically free scenario at very high
temperatures.
