Observation of the Λb0 → J/ψ pπ− decay

A bstract The first observation of the Cabibbo-suppressed decay Λ b 0 → J / ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb −1 . A prominent signal is observed and the branching fraction relative to the decay mode Λ...
