New physics reach of the decay mode $\bar{B}\to {\bar{K}}^{\ast 0}{\ell }^{+}{\ell }^{-}$

Ulrik Egede, Tobias Hurth, Joaquim Matias +2

We present a complete method to construct QCD-protected observables based on the exclusive 4-body $B$-meson decay $\bar{B}\to {\bar{K}}^{\ast 0}{\ell }^{+}{\ell }^{-}$ in the low dilepton mass re…
