Reconstruction of B0 → J/ψ KS0 and Measurement of Ratios of Branching Ratios Involving B → J/ψ K* and B+ → J/ψ K+ Academic Article uri icon


  • We report on the reconstruction of the decay mode B0→J/ΨKS0 using 19.3pb-1 of data collected by the Collider Detector at Fermilab in p-p collisions at √s=1.8TeV. A signal of 41.8±6.9 events, with a signal-to-background ratio of 9:1, is observed. Three additional decay modes B+→J/ΨK+, B0→J/ΨK*(892)0, and B+→J/ΨK*(892)+ are reconstructed. We measure three ratios of branching ratios, each one relative to the B+→J/ΨK+ mode. We also report the ratio of decay rates, γ(B→J/ΨK*)/γ(B→J/ΨK), for the vector-vector relative to the vector-pseudoscalar modes, to be 1.32±0.23(stat)±0.16(syst). © 1996 The American Physical Society.
