Anomalous Amplitudes in a Thermal Bath
Anomalous Amplitudes in a Thermal Bath
I review the implications of the axial anomaly in a thermal bath. I assume that the Adler-Bardeen theorem applies at nonzero temperature, so that the divergence of the axial current remains independent of temperature. Nevertheless, I argue that while the anomaly does not change with temperature, “anomalous” mesonic couplings do. …
