Observation of the Hadronic Transitions chi_b1,2 (2P) --> omega Upsilon(1S)

D. Cronin-Hennessy, CLEO Collaboration

The CLEO Collaboration has made the first observations of hadronic transitions among bottomonium (b-bbar) states other than the dipion transitions among upsns states. In our study…

First Measurement of $Γ (D^{*+})$

CLEO Collaboration, T. E. Coan

We have made the first measurement of the D*+ width using 9/fb of e+e- data collected near the Upsilon(4S) resonance by the CLEO II.V detector. Our method uses advanced tracking te…

Search for Direct CP Violation in $Ξ$ Hyperon Decay

D. E. Jaffe, CLEO Collaboration

Using data collected with the CLEO II detector we have performed a search for direct CP violation in the $Ξ$ hyperon system. CP violation gives rise to an asymmetry, A, between the…

Two-Body B Meson Decays to $η$ and $η^{^{'}}$ - Observation of $B \to η K^{*}$

S. J. Richichi, CLEO Collaboration

In a sample of 19 million produced B mesons we have observed decays B -> eta K*, and improved our previous measurements of B -> eta' K. The branching fractions we measure for these…
