Résumé : We provide a combined explanation of the increasingly tantalizing B-meson anomalies, both in RK(∗) and RD(∗), in the Pati-Salam model with minimal matter content. This well-known model, based on the gauge group SU(4)LC × SU(2)L × SU(2)R, naturally contains a variety of scalar leptoquarks with related and restricted couplings. In particular we show that the seesaw-motivated scalar leptoquark within the representation (10¯ ,3,1) and its right-handed parity partner (10¯ ,1,3) can solve both anomalies while making testable predictions for related observables such as B → Kνν and B → Kμτ. The solution of the RK(∗) anomaly alone can be related to a type-II seesaw neutrino mass structure. Explaining also RD(∗) requires the existence of a light right-handed neutrino, which constrains the UV structure of the model.
