Observation of the Λ b 0 → J / ψ Λ ϕ decay in proton-proton collisions at √ s = 13 TeV
© 2020 The Author The observation of the Λb0→J/ψΛϕ decay is reported using proton-proton collision data collected at s=13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity of 60fb−1. The ratio of the branching fractions B(Λb0→J/ψΛϕ)/B(Λb0→ψ(2S)Λ) is measured to b...
