### Observation of $B^+_c \rightarrow J/ψD_s^+$ and $B^+_c \rightarrow J/ψD_s^{*+}$ decays

Abstract:

The decays $B^+_c \rightarrow J/\psi D_s^+$ and $B^+_c \rightarrow J/\psi D_s^{*+}$ are observed for the first time using a dataset, corresponding to an integrated luminosity of 3$fb^{-1}$, collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of $\sqrt{s}$=7 and 8 TeV. The statistical significance for both signals is in excess of 9 standard deviations. The following ratios of branching fractions are measured to be \$BR(B^+_c \rightarrow J/\psi D_s^+)/BR(B^+_c...
