In the last year various experimental results in semileptonic B decays appeared, confirming previous hints for possible violations from lepton flavor universality at the 3-4sigma level. After discussing in general terms which kind of New Physics scenarios could explain these anomalies, I will present a simple interpretation in terms of an EFT approach, its possible underlying dynamical model, and the results of our global fit of the data. Finally, I will discuss the consequences of such a model for direct searches at the LHC and the constraints which follow.
