Anomalous Processes in Effective Chiral Theories at High Temperatures

Original · EN

We discuss chiral theories of constituent quarks interacting with bosons at high temperatures. In the chirally symmetric phase we demonstrate by applying functional methods the presence of effective anomalous couplings for e.g. πσ→ γγ, γ→ πππσ, K K → πππσ, etc., as they have recently been discussed by Pisarski.
