Measurement of the $B^0\to K^{\ast 0}{e}^{+}{e}^{-}$ branching fraction at low dilepton mass

LHCb collaboration, R. Aaij, C. Abellan Beteta +623

The branching fraction of the rate decay $B^0\to K^{\ast 0}{e}^{+}{e}^{-}$ in the dilepton mass region from 30 to 1000 MeV$/c^2$ has been measured by the LHCb experiment, using $pp$ c…
