Observation ofB+→ψ(2S)K+andB0→ψ(2S)K*(892)0decays and measurements ofB-meson branching fractions intoJ/ψandψ(2S)final states

We report the observations of the decays B{sup +}{yields}{psi}(2S)K{sup +} and B{sup 0}{yields}{psi}(2S)K*(892){sup 0} in p{ovr p} collisions at a center-of-mass energy of 1.8 TeV using a 110 pb{sup -1} data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B{sup +}{yields}J/{psi}K{sup +} and B{sup 0}{yields}J/{psi}K*(892){sup 0} and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic B-meson decays. We use the world-average branching fraction B(B{sup +}{yields}J/{psi}K{sup +}) to derive B(B{sup +}{yields}{psi}(2S)K{sup +})=(0.56{+-}0.08{+-}0.10)x10{sup -3}, B(B{sup 0}{yields}{psi}(2S)K*(892){sup 0})=(0.92{+-}0.20{+-}0.16)x10{sup -3}, and B(B{sup 0}{yields}J/{psi}K*(892){sup 0})=(1.78{+-}0.14{+-}0.29)x10{sup -3}, where the first and second uncertainties are statistical and systematic, respectively.
