Chiral anomaly in the $η^{(')} \to π^{+} π^{-} γ$ and $η^{(')} \to π^{+} π^{-} l^{+} l^{-}$ decays

M. K. Volkov, A. A. Osipov, K. Nurlan +1

We report the presence of a flavor-violating correction to the $V AAA$ -type anomaly, $δ^{(')}$ , induced by the surface terms of the anomalous quark triangle diagram, previously…

Isospin symmetry breaking and gluon anomaly

A. A. Osipov

The contribution of the electromagnetic interaction to the self-energy of pseudo-Goldstone bosons, as well as to the mixing angles and weak decay constants, is calculated in the fi…
