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…
