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…

Inclusive eta' Production from the Upsilon(1S)

CLEO Collaboration, M. Artuso

Using the CLEO II detector at CESR, we measure the eta' - gluon - gluon form-factor in Y(1S) decays. This form-factor especially at large eta' energies may provide an explanation o…

Determination of the B-bar --> D* l nu-bar Decay Width and |V_cb|

N. E. Adam

In the Standard Model, the charged current of the weak interaction is governed by a unitary quark mixing matrix that also leads to CP violation. Measurement of the Cabibbo-Kobayash…

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…

Improved Measurement of |Vcb| using B --> D* l nu Decays

R. A. Briere

We determine the weak coupling |Vcb| between the b and c quarks using a sample of 3 million BB-bar events in the CLEO detector at the Cornell Electron Storage Ring. We determine th…

Measurement of the D+ --> K*0bar l+ nu_l Branching Fraction

G. Brandenburg

Using 13.53/fb of CLEO data, we have measured the ratios of the branching fractions R+(e) = BF(D+ --> K*0bar e+ nu_e) / BF(D+ --> K- pi+ pi+), R+(mu) = BF(D+ --> K*0bar mu+ nu_mu)…

Measurement of the Ratio of Branching Fractions of the Upsilon(4S) to Charged and Neutral B Mesons

S. B. Athar, CLEO Collaboration

The ratio of charged and neutral B meson production at the Upsilon(4S), f_{+-}/f_{00}, is measured through the decays B bar -> D* l- nu_l bar, reconstructed using a partial reconst…

Improved Measurement of |V_ub| with Inclusive Semileptonic B Decays

A. Bornheim, CLEO Collaboration

We report a new measurement of the CKM parameter V_ub made with a sample of 9.7 million B B-bar events collected with the CLEO II detector. Using Heavy Quark theory, we combine the…

Further Experimental Studies of Two-Body Radiative ΥDecays

G. Masek

Continuing our studies of radiative Upsilon(1S) decays, we report on a search for Upsilon to gamma eta and Upsilon to gamma f_{J}(2220) in 61.3 pb^{-1} of e^{+}e^{-} data taken wit…
