Abstract

The relative rates of B-meson decays into J/ψ and ψ(2S) mesons are measured for the three decay modes in pp collisions recorded with the LHCb detector. The ratios of branching fractions (B) are measured to be B(B⁺ → ψ(2S)K⁺)/B(B⁺ → J/ψK⁺) = 0.594 ± 0.006(stat) ± 0.016(syst) ± 0.015(R_ψ), B(B⁰ → ψ(2S)K*⁰)/B(B⁰ → J/ψK*⁰) = 0.476 ± 0.014(stat) ± 0.010(syst) ± 0.012(R_ψ), B(B⁰_s →ψ(2S)φ)/B(B⁰_s →J/ψφ) = 0.489 ± 0.026(stat) ± 0.021(syst) ± 0.012(R_ψ), where the third uncertainty is from the ratio of the ψ(2S) and J/ψ branching fractions to μ⁺ μ⁻.
