B anomalies in an EFT approach


Bordone, M (2018). B anomalies in an EFT approach. Il Nuovo Cimento C, 1-2:35.

Abstract

We present a general EFT framework based in U(2)n flavour symmetry applied to the light generations of SM fermions to address the hints of Lepton Flavour Universality violation in B decays observed in the recent years. In particular we analyse the constraints from the low energy observables in B and τ physics. We show that a consistent picture can be achieved introducing a moderate fine tuning and additional dynamical assumptions which aim to the New Physics (NP) being coupled mostly to the third generation of SM fermions.
