Abstract:
We report the observations of the decays B+ → ψ(2S)K+ and B0 → ψ(2S)K*(892)0 in pp̄ collisions at a center-of-mass energy of 1.8 TeV using a 110 pb-1 data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B+ → J/ψK+ and B0 → J/ψK*(892)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+ → J/ψK+) to derive ℬ(B+ → ψ(2S)K+) = (0.56±0.08±0.10) × 10-3, ℬ(B0 → ψ(2S)K*(892)0) = (0.92±0.20±0.16) × 10-3, and ℬ(B0 → J/ψK*(892)0) = (1.78±0.14±0.29) × 10-3, where the first and second uncertainties are statistical and systematic, respectively.Radio observations of IRAS-selected Southern hemisphere classical Be stars
