Physical Review D - Particles, Fields, Gravitation and Cosmology 57:9 (1998) 5363-5369
Abstract:
Using (Formula presented) of data accumulated at the (Formula presented) by the CLEO-II detector, corresponding to (Formula presented) (Formula presented) pairs, we have searched for the color-suppressed (Formula presented) hadronic decay processes (Formula presented) where (Formula presented) is a light neutral meson (Formula presented) (Formula presented) η, (Formula presented) or ω. The (Formula presented) mesons are reconstructed in (Formula presented) and the (Formula presented) mesons in (Formula presented) (Formula presented) and (Formula presented) decay modes. No obvious signal is observed. We set 90% C.L. upper limits on these modes, varying from (Formula presented) for (Formula presented) to (Formula presented) for (Formula presented). © 1998 The American Physical Society.Search for flavor-changing neutral current decays of the top quark in pp collisions at √s = 1.8 TeV

Abstract:
We search for the flavor-changing neutral current decays of the top quark t → λ and t → qZ (here represents the c and u quarks) in pp collisions at √s = 1.8 TeV. We use a dataset (∫ L dt˜ 110pb-1) collected during the 1992-1995 run of the Collider Detector at Fermilab. We set 95% confidence level limits on the branching fractions B(t → qλ) < 3.2% and B(t → qZ) < 33%, consistent with the standard model. © 1998 The American Physical Society.Search for the rare decay W± → Ds plusmnγ in pp̄ collisions at √s = 1.8 TeV

Abstract:
Using data collected by the CLEO II detector at a center-of-mass energy on or near the (Formula presented) resonance, we have determined the 90% confidence level upper limit (Formula presented) for electrons with momentum above (Formula presented) We have also obtained the limit (Formula presented) at the 90% confidence level and measured the ratio (Formula presented). © 1998 The American Physical Society.A limit on the mass of the ντ
