Charge Symmetry Breaking in Pion-Nucleon Coupling Constants Induced by Axial Anomaly
N. I. Kochelev
文献摘要
The contribution of axial anomaly to charge symmetry breaking in pion-nucleon coupling constants is calculated within instanton model for QCD vacuum. It has been demonstrated that the contribution is large and allows to explain Nolen-Schiffer anomaly.
