Observation of a new excited charm-strange meson $D_{s 1} (2933)^{+}$ in $B^{0} \to D^{+} D^{-} K^{+} I ¨ ^{-}$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1114

A new excited charm-strange meson is observed through an amplitude analysis of the full phase space of $B^{0} \to D^{+} D^{-} K^{+} I ¨ ^{-}$ decays. The analysis is based on a proton-proton co…

Improved measurement of $I^\cdot / I^\cdot^{'}$ mixing in $B_{(s)}^{0} \to J / I ¨ I^\cdot^{(')}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1182

Branching fraction ratios between the decays $B_{(s)}^{0} \to J / I ¨ I^\cdot^{(')}$ are measured using proton-proton collision data collected by the LHCb experiment at centre-…
