U-A(1) symmetry restoration in QCD with N-f flavors

Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under U(N-f) X U(N-f) rather than SU(N-f)XSU(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.
