Combined explanations of $B$-physics anomalies, $(g-2{)}_{e,\mu }$ and neutrino masses by scalar leptoquarks

Abstract

We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons (electron and muon) and $B$-physics anomalies ($R_{K^{(\ast )}}$ and $R_{D^{(\ast )}}$). The model consists of $\text{SU}(2{)}_L$ singlet leptoquark $S_1\sim (\bar{3},1,1/3)$, doublet leptoquark ${\tilde{R}}_2\sim (3,2,1/6)$ and triplet leptoquark $S_3\sim (\bar{3},3,1/3)$. We combine the constraints arising from the low-energy lepton flavor violation, meson decay and mixing observables. We perform a detailed phenomenological analysis and identify the minimized texture of leptoquark Yukawa matrices to accommodate a unified explanation of the anomalies and neutrino oscillation data.
