The Coupling of the Pion to Two Gauge Fields and to Leptons in a Dynamically Broken Gauge Theory
arXiv:hep-ph/9306285 · doi:10.1142/S0217732394002884
Abstract
We show how a spontaneously broken gauge theory of fermions endowed with a composite scalar multiplet becomes naturally anomaly-free, and yet describes the correct couplings of the pion to two gauge fields and to leptons: the first coupling is the same as computed from the chiral anomaly, and the second identical with that obtained from the `Partially Conserved Axial Current' hypothesis. For the sake of simplicity, we only study here the abelian case.
