The γπ → ππ anomaly from lattice QCD and dispersion relations

The γπ → ππ anomaly from lattice QCD and dispersion relations

Abstract We propose a formalism to extract the γπ → ππ chiral anomaly F 3π from calculations in lattice QCD performed at larger-than-physical pion masses. To this end, we start from a dispersive representation of the γ (*) π → ππ amplitude, whose main quark-mass dependence arises from the ππ scatter...
