Measurement of Lepton Momentum Moments in the Decay bar{B} \to X \ell \barν and Determination of Heavy Quark Expansion Parameters and |V_cb|

A. H. Mahmood

We measure the primary lepton momentum spectrum in B-bar to X l nu decays, for p_l > 1.5 GeV/c in the B rest frame. From this, we calculate various moments of the spectrum. In part…

J-ψProduction via χ_c Decays in 920 GeV pA Interactions

B Collaboration

Using data collected by the HERA-B experiment, we have measured the fraction of Jψ's produced via radiative chi_c decays in interactions of 920 GeV protons with carbon and titanium…

First Observation of the Exclusive Decays Lambda_c to Lambda pi+pi+pi-pi0 and Lambda_c to Lambda omega pi+

D. Cronin-Hennessy

Using data recorded by the CLEO III detector at CESR, we report on the first measurements of the branching fractions for decays of the Lambda_c^+ charmed baryon into (Lambda pi+ pi…

Search for Neutrinoless tau Decays Involving the K_S^0 Meson

S. Chen, CLEO Collaboration

We have searched for lepton flavor violating decays of the tau lepton with one or two KS0 mesons in the final state. The data used in the search were collected with the CLEO II and…

Measurement of Exclusive B Decays to Final States Containing a Charmed Baryon

S. A Dytman, CLEO Collaboration

Using data collected by the CLEO detector in the Upsilon(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Lambda_c^+ p-bar n…

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…
