| Shrnutí: | Title screen Study of J/ψ meson production inside jets in pp collisions at √s =8TeVThe observation of the Λb0→J/ψΛϕ decay is reported using proton-proton collision data collected at √s = 13 TeVby 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 be (8.26±0.90(stat)±0.68(syst)±0.11(B))×10−2, where the first uncertainty is statistical, the second is systematic, and the last uncertainty reflects the uncertainties in the world-average branching fractions of ϕ and ψ(2S) decays to the reconstructed final states. |
