Observation of new excited ${\Sigma }_c^0$ states in the $B^{-}\to {\Lambda }_c^{+}\overline{p}{\pi }^{-}$ decay

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

An amplitude analysis of the $B^{-}\to {\Lambda }_c^{+}\overline{p}{\pi }^{-}$ decay is performed using proton-proton collision data, corresponding to an integrated luminosity of $9\text{…
