Description
First, the importance of the chiral anomaly in the QCD vacuum is briefly reviewed. Besides pseudoscalar mesons, it may affect other resonances. To this end, a mathematical object called `polydeterminant' is introduced. Next, the role of the chiral anomaly at nonzero temperature is investigated. In particular, the Columbia plot (the order of the phase transition in dependence of the quark masses) is strongly affected by the precise realization of the chiral anomaly.
