Longitudinal short-distance constraints for the hadronic light-by-light contribution to with large- Regge models
Gilberto Colangelo, Franziska Hagelstein, Martin Hoferichter +2
While the low-energy part of the hadronic light-by-light (HLbL) tensor can be constrained from data using dispersion relations, for a full evaluation of its contribution to the ano…

Short-distance constraints on hadronic light-by-light scattering in the anomalous magnetic moment of the muon
Gilberto Colangelo, Franziska Hagelstein, Martin Hoferichter +2
A key ingredient in the evaluation of hadronic light-by-light (HLbL) scattering in the anomalous magnetic moment of the muon concerns short-distance constraints (SDCs) th…
