Search for High Mass Photon Pairs in p-pbar --> gamma-gamma-jet-jet Events at sqrt(s)=1.8 TeV

D0 Collaboration, B. Abbott

A search has been carried out for events in the channel p-barp --> gamma gamma jet jet. Such a signature can characterize the production of a non-standard Higgs boson together with…

Observation of Two Narrow States Decaying into $Ξ_{c}^{+} γ$ and $Ξ_{c}^{0} γ$

C. P. Jessop

We report the first observation of two narrow charmed strange baryons decaying to $Ξ_{c}^{+} γ$ and $Ξ_{c}^{0} γ$ , respectively, using data from the CLEO II detector at CESR. We interpret th…

First Observation of the Decay $τ^{-} \to K^{*-} η ν_{τ}$

M. Bishai

Using data recorded by the CLEO-II detector at CESR, we report the first measurement of the branching fraction for the decay of $τ^{-}$ into $K^{*-} η ν_{τ}$ . The measured branching frac…

First Observation of $Υ (1 S) \to γ π π$

A. Anastassov

We report on a study of exclusive radiative decays of the Upsilon(1S) resonance collected with the CLEO-II detector operating at CESR. We present the first observation of the radia…

Observation of High Momentum $η^{'}$ Production in B Decay

T. E. Browder

We report the first observation of $B \to η^{'} X$ transitions with high momentum $η^{'}$ mesons. We observe $39.0 \pm 11.6$ B decay events with $2.0 < p_{η^{'}} < 2.7$ GeV/c, the high momentu…

First Observation of the Cabibbo Suppressed Decay $B^{+} \to D ˉ^{0} K^{+}$

M. Athanas

We have observed the decay of the $B^{-}$ meson into $D^{0} K^{-}$ , using 3.3 million $B B ˉ$ pairs collected with the CLEO II detector at the Cornell Electron Storage Ring. We find th…
