We show that a model with a scalar leptoquark of hypercharge $Y=1/6$ which includes the light right-handed neutrinos, can successfully describe both of the $B$-physics anomalies, $R_K^{\rm exp} < R_K^{\rm SM}$ and $R_D^{\rm exp} > R_D^{\rm SM}$. We discuss the corresponding low energy effective theory and, after using the known experimental data as constraints, we show that the model is viable and that it offers several predictions which can be tested experimentally.

Correlative study of flavor anomalies and dark matter in the light of scalar leptoquark
hep-ph 2024-09 unverdicted novelty 3.0

A U(1)_{Le-Lμ} extended SM with scalar leptoquark explains b→s anomalies via Z', leptoquark and new fermions while the lightest neutral fermion serves as DM, with constraints analyzed from B decays and DM observables.
