The ratio of the branching fractions B(Lambda(0)(b) -> J/psi Lambda phi)/B(Lambda(0)(b) > psi(2S)Lambda) is measured to be (8.26 +/- 0.90 (stat) +/- 0.68 (syst) +/- 0.11 (B)) x 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 phi and psi(2S) decays to the reconstructed final states.eninfo:eu-repo/semantics/openAccessCMSB physicsHeavy-flavor spectroscopyComputingObservation of the Lambda(0)(b) -> J/psi Lambda phi decay in proton-proton collisions at root s=13 TeVArticle2-s2.0-8507852900410.1016/j.physletb.2020.135203Q2WOS:000515091400050
