Abstract: A bstractThe 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,… read more here.

Abstract: Hadronic light-by-light (HLbL) scattering defines one of the critical contributions in the Standard Model prediction of the anomalous magnetic moment of the muon. In this Letter, we present a complete evaluation using a dispersive formalism,… read more here.

Abstract: We perform a lattice QCD calculation of the hadronic light-by-light contribution to $$(g-2)_\mu $$ at the SU(3) flavor-symmetric point $$m_\pi =m_K\simeq 420\,$$ MeV. The representation used is based on coordinate-space perturbation theory, with all QED… read more here.
