Relative rates of B meson decays into psi(2S) and J/psi mesons (Art. No. 111102)
Original language description
We report on a study of the relative rates of B meson decays into psi(2S) and J/psi mesons using 1.3 fb(-1) of p (p) over bar collisions at root s = 1.96 TeV recorded by the D0 detector operating at the Fermilab Tevatron Collider. We observe the channelsB-s(0) -} psi(2S)phi, B-s(0) -} J/psi phi, B- /- -} psi(2S)K- /-, and B- /- -} J/psi K- /- and we measure the relative branching fractions for these channels to be B(B-s(0) -} psi(2S)phi)/B(B-s(0) -} J/psi phi)=0.53 /- 0.10(stat) /- 0.07(syst) /- 0.06(B), B(B -} psi(2S)K )/B(B -} J/psi K )=0.63 /- 0.05(stat) /- 0.03(syst) /- 0.07(B), where the final error corresponds to the uncertainty in the J/psi and psi(2S) branching ratio into two muons.
