Observation of new excited $\hat{I}{\pounds }_c^0$ states in the $B^{-}\to \hat{I}{›}_c^{+}\overline{p}\ddot{I}{€}^{-}$ decay

LHCb collaboration, R. Aaij, M. Abdelfatah +1100

An amplitude analysis of the $B^{-}\to \hat{I}{›}_c^{+}\overline{p}\ddot{I}{€}^{-}$ decay is performed using proton-proton collision data, corresponding to an integrated luminosity of $9\tex…
