Search for lepton-number-violating $B^{-}\to D^{(\ast )+}{\mu }^{-}{\mu }^{-}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1188

A search is performed for lepton-number-violating $B^{-}\to D^{(\ast )+}{\mu }^{-}{\mu }^{-}$ decays, using data collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy…
