Impact of Hadronic Resonances on $B\to K^{(\ast )}\ddot{I}{„}^{+}\ddot{I}{„}^{-}$ decays

Guillermo BaltÃ, Andreas Crivellin, Rafel Escribano +2

Neutral-current semileptonic $B$ decays are plagued by hadronic resonances across the dilepton invariant-mass squared spectrum, $q^2$. For light leptons, $\ell =e,\hat{I}¼$, these resonan…
