We consider the possibility of explaining the recent RK and RK∗ anomalies in a two-Higgs doublet model, known as aligned, combined with a low-scale seesaw mechanism generating light neutrino masses and mixings. In this class of models, a large Yukawa coupling allows for significant nonuniversal leptonic contributions, through box diagrams mediated by charged Higgs bosons and right-handed neutrinos, to the b→s+- transition that can then account for both RK and RK∗ anomalies.

Abstract
We consider the possibility of explaining the recent RK and RK∗ anomalies in a two-Higgs doublet model, known as aligned, combined with a low-scale seesaw mechanism generating light neutrino masses and mixings. In this class of models, a large Yukawa coupling allows for significant nonuniversal leptonic contributions, through box diagrams mediated by charged Higgs bosons and right-handed neutrinos, to the b→s+- transition that can then account for both RK and RK∗ anomalies.File in questo prodotto:
