abstract

  • We report on the reconstruction of the decay mode B0J/KS0 using 19.3pb-1 of data collected by the Collider Detector at Fermilab in p-p collisions at s=1.8TeV. A signal of 41.86.9 events, with a signal-to-background ratio of 9:1, is observed. Three additional decay modes B+J/K+, B0J/K*(892)0, and B+J/K*(892)+ are reconstructed. We measure three ratios of branching ratios, each one relative to the B+J/K+ mode. We also report the ratio of decay rates, (BJ/K*)/(BJ/K), for the vector-vector relative to the vector-pseudoscalar modes, to be 1.320.23(stat)0.16(syst). 1996 The American Physical Society.
