Reassessing the discovery potential of the $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ decays in the large-recoil region: SM challenges and BSM opportunities

Sebastian Jäger, Jorge Martin Camalich

We critically examine the potential to disentangle Standard Model (SM) and New Physics (NP) in $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$ and $B\to K^{\ast }{e}^{+}{e}^{-}$ decays, focusing on $(i)$ the LHCb anomaly,…
