Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under U(Nf)×U(Nf) rather than SU(Nf)×SU(Nf). 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 Nf flavors in the high-temperature chirally restored phase.
