New measurements of $B_{c}^{+}$ decays into single charm final states

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1147

Using proton-proton collision data corresponding to an integrated luminosity of $9 fb^{- 1}$ collected by the LHCb experiment, searches are performed for $B_{c}^{+}$ mesons d…
