Abstract

Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under U(N_f)×U(N_f) rather than SU(N_f)×SU(N_f). We supplement their argument by including the contributions from topologically nontrivial gauge-field configurations and discuss how the conclusions are modified. General statements are made concerning the particle spectrum of QCD with light N_f flavors in the high-temperature chirally restored phase.
