Interplay between flavor anomalies and neutrino properties

Abstract

A minimal extension of the Standard Model (SM) featuring two scalar leptoquarks, an SU(2) doublet with hypercharge 1/6 and a singlet with hypercharge 1/3, is proposed as an economical benchmark model for studies of an interplay between flavor physics and properties of the neutrino sector. The presence of such type of leptoquarks radiatively generates neutrino masses and offers a simultaneous explanation for the current B-physics anomalies involving b→cℓνℓ decays. The model can also accommodate both the muon magnetic moment and the recently reported W-mass anomalies, while complying with the most stringent lepton flavor-violating observables.
