Abstract:

We present the first observation of the decay B →J/ψϕK Using 9.6 ×106BB¯meson pairs collected with the CLEO detector, we have observed ten fully reconstructed B →J/ψϕK candidates, whereas the estimated background is 0.5 ±0.2event. We obtain a branching fraction of B(B →J/ψϕK)=(8.8−3.0+3.5[stat]±1.3[syst])×10−5This is the first observed B meson decay requiring the creation of an additional ss¯quark pair. © 2000 The American Physical Society.

Abstract:

From a data sample of 29058 τ+→π±π+π -π0ντdecays observed in the CLEO detector we derive a 95% confidence upper limit on the tau neutrino mass of 28 MeV. ©2000 The American Physical Society.

Abstract:

Events collected by the Collider Detector at Fermilab (CDF) with an energetic jet plus large missing transverse energy can be used to search for physics beyond the standard model. We see no deviations from the expected backgrounds and set upper limits on the production of new processes. We consider in addition the production of light gravitinos and set a limit at 95% F ≥ 217GeV, which excludes gravitino masses smaller than 1.1 × 10−5eV/c2. © 2000 American Physical Society.
