Differential decay rate of $B^{+} \to J / I ¨ K^{+}$ with the LHCb Upgrade I experiment

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1183

The normalised decay rate of $B^{+} \to J / I ¨ (\to I^¼^{+} I^¼^{-}) K^{+}$ is measured as a function of the lepton helicity angle using a data sample corresponding to an integrated luminosity o…

Observation of the decay $I ¨ _{c 1} (3872) \to J / I ¨ I^¼^{+} I^¼^{-}$

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1184

The first observation of the $I ¨ _{c 1} (3872) \to J / I ¨ I^¼^{+} I^¼^{-}$ decay is reported using proton-proton collision data recorded with the LHCb detector corr…
