ON DECAY AND CANCELLATION OF AXIAL ANOMALY IN TRANSITION AMPLITUDE FOR MASSIVE FERMIONS

Open publisher page 0 citations

Abstract

decay amplitude is considered and proven to be zero due to properties of polarization vectors and Bose statistics. Triangular diagrams for a pseudoscalar and processes with massive fermions in the loop are explicitely calculated. In the Standard Model axial anomaly vanishes in the sum of these diagrams as boson is mixed with one of the Goldstone bosons.
