Abstract
The first observation of the Cabibbo-suppressed decay Λ0b→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 Λ0b→J/ψpK− is determinedFile in questo prodotto:
