Abstract

We report on a study of the relative rates of B meson decays into ψ(2S) and J/ψ mesons using 1.3fb1 of pp¯ collisions at s=1.96TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We observe the channels Bs0ψ(2S)ϕ, Bs0J/ψϕ, B±ψ(2S)K±, and B±J/ψK± and we measure the relative branching fractions for these channels to be B(Bs0ψ(2S)ϕ)B(Bs0J/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.
