Abstract We show how nonzero Majorana neutrino masses can be radiatively generated by extending the MSSM with leptoquark chiral multiplets without violating R-parity. It is found that, with these particles, the R-parity conservation does not imply lepton number conservation. Neutrino masses generated at a one-loop level are closely related to the down quark mass matrix. The ratio of neutrino mass-squared splittings Δm 2 ν 2 – ν 1 / Δm 2 ν 3 – ν 2 obtained is naturally close to Δm 2 s − d / Δm 2… Expand

One leptoquark to unify them? Neutrino masses and unification in the light of (g − 2)μ, RD(⋆) and RK anomalies
Abstract Leptoquarks have been proposed as a possible explanation of anomalies in B ¯ ↦ D ⁎ τ ν ¯ decays, the apparent anomalies in ( g − 2 ) μ experiments and a violation of lepton universality.Expand

From the Trees to the Forest: A Review of Radiative Neutrino Mass Models
A plausible explanation for the lightness of neutrino masses is that neutrinos are massless at tree level, with their mass (typically Majorana) being generated radiatively at one or more loops. TheExpand
