The ratios of branching fractions ( B) are measured to be where the third uncertainty is from the ratio of the ψ(2S) and J/ψ branching fractions to μ + μ −.9 p.application/pdfengcc by (c) LHCb Collaboration, 2012http://creativecommons.org/licenses/by/3.0/AstronomiaAstrofísicaCosmologiaEnergia nuclearFísica nuclearHadronsAstronomyAstrophysicsCosmologyNuclear energyNuclear physicsHadronsinfo:eu-repo/semantics/article6196322014-10-20info:eu-repo/semantics/openAccess25814846
