Title: Common origin of neutrino masses and R D ( * ) , R K ( * ) anomalies

Journal Article · · Physical Review D

In this work, we present a solution to the persistent tensions in the decay observables $$R_{D^{(*)}}$$ and $$R_{K^{(*)}}$$ by introducing a $$SU(2)_L$$ doublet and a $$SU(2)_ L$$ triplet scalar leptoquarks (LQs) that reside at the TeV energy scale. Neutrinos that remain massless in the Standard Model receive naturally small masses at one-loop level via the propagation of the same LQs inside the loop. Such a common origin of apparently disjoint phenomenological observations is appealing, and we perform a comprehensive analysis of this setup. We identify the minimal Yukawa textures required to accommodate these flavor anomalies and to successfully incorporate neutrino oscillation data while being consistent with all experimental constraints. This scenario has the potential to be tested at the experiments by the future improved measurements in the lepton flavor violating processes. Furthermore, proper explanations of these flavor anomalies predict TeV scale LQs that are directly accessible at the LHC.
