Longitudinal short-distance constraints for the hadronic light-by-light contribution to (g − 2) μ with large-N c Regge models

Longitudinal short-distance constraints for the hadronic light-by-light contribution to (g − 2) μ with large-N c Regge models

Abstract 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 anomalous magnetic moment of the muon (g − 2) μ also mixed- and high-energy regions need to be estimated. Both can...
