This Letter reports the observation and mass measurement of fully reconstructed B(s)0 mesons through the decay chain B(s)0 --> J/psiphi, J/psi --> mu+mu-, phi --> K+K- using data obtained at the Collider Detector at Fermilab in ppBAR collisions at square-root s = 1.8 TeV. A signal of 14.0 +/- 4.7 events is observed. Comparison of the B(s)0 signal with the kinematically similar decays B+ --> J/psiK+ and B0 --> J/psiK*(892)0 is presented. The mass of the B(s)0 meson is determined to be 5383.3 +/- 4.5 (stat) +/- 5.0 (syst) MeV/c2.

Abstract

This Letter reports the observation and mass measurement of fully reconstructed B(s)0 mesons through the decay chain B(s)0 --> J/psiphi, J/psi --> mu+mu-, phi --> K+K- using data obtained at the Collider Detector at Fermilab in ppBAR collisions at square-root s = 1.8 TeV. A signal of 14.0 +/- 4.7 events is observed. Comparison of the B(s)0 signal with the kinematically similar decays B+ --> J/psiK+ and B0 --> J/psiK*(892)0 is presented. The mass of the B(s)0 meson is determined to be 5383.3 +/- 4.5 (stat) +/- 5.0 (syst) MeV/c2.
