Dispersion relation for hadronic light-by-light scattering: two-pion contributions
In this third paper of a series dedicated to a dispersive treatment of the hadronic light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate states in the HLbL contribution to the anomalous magnetic moment of the muon (g − 2)$_{μ}$ , including a detailed discussio...
