Resumen
One of the most significant direct evidences of physics beyond the standard model (SM) are the recently observed anomalies in B meson decays, which suggest a lepton flavor universality (LFU) violation. Assuming that those anomalies are not the product of systematic errors, they can be explained by a vector leptoquark (LQ) (3, 1)2 / 3 , which can arise from grand unification theories such as the Pati-Salam model. We study a model within the Pati-Salam unification framework that aims at explaining the LFU violations. It is based on the local gauge group SU(4)L × SU(4)R × SU(2)L × U(1)′ and its key feature is that SU(4)R breaks at a much higher energy scale than SU(4)L , avoiding right handed flavor changing currents and allowing a mass of the LQ as low as 10 TeV. The model does not require the introduction of quarks or leptons mixings with new vector-like fermions. We present a detailed study of this model, obtain constraints from the C9 and C10 pseudo-observables, and constrast them against a model independent analysis.
