One leptoquark to unify them? Neutrino masses and unification in the light of (g−2)μ, RD(⋆) and RK anomalies
Leptoquarks have been proposed as a possible explanation of anomalies in B¯↦D⁎τν¯ decays, the apparent anomalies in (g−2)μ experiments and a violation of lepton universality. Motivated by this, we examine other motivations of leptoquarks: radiatively induced neutrino masses in the presence of a disc...

Leptoquarks have been proposed as a possible explanation of anomalies in B¯↦D⁎τν¯ decays, the apparent anomalies in (g−2)μ experiments and a violation of lepton universality. Motivated by this, we examine other motivations of leptoquarks: radiatively induced neutrino masses in the presence of a discrete symmetry that prevents a tree level see-saw mechanism, gauge coupling unification, and vacuum stability at least up to the unification scale. We present a new model for radiatively generating a neutrino mass which can significantly improve gauge coupling unification at one loop. We discuss this, and other models in the light of recent work on flavour anomalies. |
