Triangle anomaly at a nonzero temperature in quantum chromodynamics
Krasnikov N. V.
An analysis based on the Adler-Bell-Jackiw equation for a nonzero temperature shows that the temperature (TF) at which the chiral symmetry is restored is greater than or equal to the deconfinement temperature Tc. At temperatures in the interval Tc <T<TF, massless quarks acquire a nonzero dynamic mass.
