Constraining the new contributions to electron g − 2 in a radiative neutrino mass model

We examine electron and muon anomalous magnetic dipole moments within a radiative neutrino mass model featuring TeV-scale scalar leptoquarks S ( 3 , 1 , − 1 / 3 ) and R ( 3 , 2 , 1 / 6 ) . We utilize textures with decoupling electron and muon sectors, so that both electron and muon anomalous magnetic dipole moments could receive internal chiral enhancements from different heavy up-type quarks while in the same time evading the stringent μ → e γ constraint. A successful fit to neutrino oscillation data requires the simultaneous presence of one- and two-loop neutrino mass contributions. This severely constrains the parameter space of the model, which results in a negligible new physics correction to the muon g − 2 . The electron g − 2 discrepancy implied by the rubidium experiment, on the other hand, can be resolved within 2 σ uncertainty provided that neutrino mass ordering is inverted. Lepton-flavor-violating tau decay rates, such as τ → e γ and τ → 3 e , are predicted to be within the sensitivities of next-generation experiments.
