Observation of the Decay Omega_C^0 --> Omega- e+ nu_e
R. Ammar, CLEO Collaboration
Using the CLEO detector at the Cornell Electron Storage Ring, we have observed the Omega_c (css ground state) in the decay Omega_c -> Omega- e+ nu. We find a signal of 11.4 +- 3.8…
Measurement of the Masses and Widths of the Sigma_c^++ and Sigma_c^0 Charmed Baryons
M. Artuso, CLEO Collaboration
Using data recorded by the CLEO II and CLEO II.V detector configurations at CESR, we report new measurements of the masses of the Sigma_c^{++} and Sigma_c^0 charmed baryons, and th…
Branching Fraction and Photon Energy Spectrum b -> s gamma
S. Chen, CLEO Collaboration
We have measured the branching fraction and photon energy spectrum for the radiative penguin process b -> s gamma. We find BR(b -> s gamma) = (3.21 +- 0.43 +- 0.27 +0.18 -0.10) 10^…
Improved Upper Limits on the FCNC Decays and
S. Anderson, CLEO Collaboration
We have searched a sample of 9.6 million BBbar events for the flavor-changing neutral current decays B -> K l^+ l^- and B -> K^*(892) l^+ l^-. We subject the latter decay to the re…
Rate Measurement of and Constraints on Mixing
G. Brandenburg, CLEO Collaboration
We present an observation and rate measurement of the decay D0 -> K+pi-pi0 produced in 9/fb of e+e- collisions near the Upsilon(4S) resonance. The signal is inconsistent with an up…
Experimental Investigation of the Two-Photon Widths of the and the Mesons
B. I. Eisenstein, CLEO Collaboration
Using 12.7 of data collected with the CLEO detector at CESR, we observed two-photon production of the states and in their decay to $π^+ π^- π…
