Three-pion contribution to hadronic vacuum polarization

Three-pion contribution to hadronic vacuum polarization

Abstract We address the contribution of the 3π channel to hadronic vacuum polarization (HVP) using a dispersive representation of the e + e − → 3π amplitude. This channel gives the second-largest individual contribution to the total HVP integral in the anomalous magnetic moment of the muon (g − 2) μ...
