Evidence of a $J / ψ Λ$ structure and observation of excited $Ξ^{-}$ states in the $Ξ_{b}^{-} \to J / ψ Λ K^{-}$ decay

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

First evidence of a structure in the $J / ψ Λ$ invariant mass distribution is obtained from an amplitude analysis of $Ξ_{b}^{-} \to J / ψ Λ K^{-}$ decays. The observed s…
