Observation of the decay Bs0→J/ψ φ in p¯p collisions at √s =1.8 TeV Academic Article uri icon


  • This Letter reports the observation and mass measurement of fully reconstructed Bs0 mesons through the decay chain Bs0J/ , J/+-, K+K- using data obtained at the Collider Detector at Fermilab in p»p collisions at s =1.8 TeV. A signal of 14.04.7 events is observed. Comparison of the Bs0 signal with the kinematically similar decays B+J/ K+ and B0J/ K*(892)0 is presented. The mass of the Bs0 meson is determined to be 5383.34.5(stat)5.0(syst) MeV/c2. © 1993 The American Physical Society.
