Observation of lambda 0b  → psi(2S)pK- and lambda 0b  → J/psiπ + π -pK- decays and a measurement of the lambda 0b baryon mass

Show other versions (3)

The decays Λb0 → ψ(2S)pK− and Λb0 → J/ψπ+π−pK− are observed in a data sample corresponding to an integrated luminosity of 3 fb−1, collected in proton-proton collisions at 7 and 8 TeV centre-of-mass energies by the LHCb detector. The ψ(2S) mesons are reconstructed through the decay modes ψ(2S) → μ+μ−...
