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…

First branching fraction measurement of the suppressed decay $Ξ_{c}^{0} \to π^{-} Λ_{c}^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The $Ξ_{c}^{0}$ baryon is unstable and usually decays into charmless final states by the $c \to s u d$ transition. It can, however, also disintegrate into a $π^{-}$ meson and a…

Study of the $ψ_{2} (3823)$ and $χ_{c 1} (3872)$ states in $B^{+} \to (J ψ π^{+} π^{-}) K^{+}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +956

The decays $B^{+} \to J / ψ π^{+} π^{-} K^{+}$ are studied using a data set corresponding to an integrated luminosity of 9fb $^{- 1}$ collected with the LHCb detector in proton-proton co…
