Reading the footprints of the B-meson flavor anomalies

Claudia Cornella, Darius A. Faroughy, Javier Fuentes-Martin +2

Motivated by the recent LHCb announcement of a $3.1 σ$ violation of lepton-flavor universality in the ratio $R_{K} = Γ (B \to K μ^{+} μ^{-}) /Γ (B \to K e^{+} e^{-})$ , we present an updated, comprehen…

The LFU Ratio $R_{π}$ in the Standard Model and Beyond

Marzia Bordone, Claudia Cornella, Gino Isidori +1

We discuss the possibility of performing precise tests of $μ / e$ universality in $B \to π ℓ^{+} ℓ^{-}$ decays. We show that in wide regions of the dilepton invariant mass spectrum th…
