Hadronic light-by-light contribution to : a dispersive approach
Gilberto Colangelo, Martin Hoferichter, Massimiliano Procura +1
After a brief introduction on ongoing experimental and theoretical activities on , we report on recent progress in approaching the calculation of the hadronic light-by-lig…
Dispersion relation for hadronic light-by-light scattering: two-pion contributions
Gilberto Colangelo, Martin Hoferichter, Massimiliano Procura +1
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 sta…
Rescattering effects in the hadronic-light-by-light contribution to the anomalous magnetic moment of the muon
Gilberto Colangelo, Martin Hoferichter, Massimiliano Procura +1
We present a first model-independent calculation of intermediate states in the hadronic-light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon $(g-2)_…
