Abstract

The relative rates of B-meson decays into J/Psi and Psi(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+ -> Psi(2S) K+)/B(B+ -> J/Psi K+) = 0.594+-0.006(stat)+-0.016(syst)+-0.015(R_Psi), B(B0 -> Psi(2S) K*0)/B(B0 -> J/Psi K*0) = 0.476+-0.014(stat)+-0.010(syst)+-0.012(R_Psi), B(Bs0 -> Psi(2S) phi)/B(Bs0 -> J/Psi phi) = 0.489+-0.026(stat)+-0.021(syst)+-0.012(R_Psi), where the third uncertainty is from the ratio of the Psi(2S) and J/Psi branching fractions to mu+mu-.
