Anomalous electromagnetic processes at high temperatures

Abstract

Chiral theories of constituent quarks interacting with bosons and photons at high temperatures are studied. In the expected chirally symmetric phase effective electromagnetic anomalous couplings for e.g. $\pi \sigma \to \gamma \gamma ,\gamma \to \pi \pi \pi \sigma ,$ etc., are derived by applying functional methods.
