Dispersion relation for hadronic light-by-light scattering: pion pole

Abstract The pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon (g − 2) μ is fully determined by the doubly-virtual pion transition form factor. Although this crucial input quantity is, in principle, directly accessible in experiment, a complete...
