Following the Footprints of the B-physics Anomalies

Recent B-meson data show a reinforced set of deviations from the Standard Model predictions, pointing to violations of lepton flavor universality. I will critically review these data and discuss their theoretical interpretation, including their possible connection to the hierarchical pattern of fermions masses and mixing angles. To this end, I will first interpret the data following an effective field theory approach and later discuss possible UV completions. Complementary constraints and implications for direct searches at LHC will also be discussed.
