Measurement of the $B \to D ℓ ν$ Branching Fractions and Form Factor

J. Bartelt

Using a sample of 3.3 million B-meson decays collected with the CLEO detector at the Cornell Electron Storage Ring, we have studied $B^{-} \to D^{0} ℓ ν$ and $\bar{B}^0 \to D^+ \ellν…

First Search for CP Violation in Tau Lepton Decay

S. Anderson

Using the CLEO II detector we have performed the first search for $C P$ violation in tau lepton decay. CP violation in lepton decay does not occur in the minimal standard model but…

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…

A Limit on the Mass of the $ν_{τ}$

R. Ammar, CLEO Collaboration et al

A limit on the mass of the tau neutrino is derived from 4.5 million tau pairs produced in an integrated luminosity of 5.0 fb^{-1} of electron-positron annihilation to tau pairs at…

Measurement of the Mass Splittings between the $b b ˉ χ_{b, J} (1 P)$ States

K. Edwards

We present new measurements of photon energies and branching fractions for the radiative transitions: Upsilon(2S)->gamma+chi_b(J=0,1,2). The masses of the chi_b states are determin…
