Abstract

We report on a study of the relative rates of B meson decays into ψ(2S) and J/ψ mesons using 1.3fb-1 of pp̅ collisions at √s=1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We observe the channels Bs0→ψ(2S)Φ, Bs0→J/ψΦ, B±\→ψ(2S)K±, and B±→J/ψK± and we measure the relative branching fractions for these channels to be B(Bs0→ψ(2S)Φ)/B(Bs0→J/ψΦ)=0.53±0.10(stat)±0.07(syst)±0.06(B), B(B±→ψ(2S)K±)/B(B±→J/ψK±)=0.63± 0.05(stat)±0.03(syst)±0.07(B),where the final error corresponds to the uncertainty in the J/Ψ and Ψ(2S) branching ratio into two muons.
