Semileptonic Branching Fraction of Charged and Neutral B Mesons

The CLEO collaboration

An examination of leptons in $Υ (4 S)$ events tagged by reconstructed $B$ decays yields semileptonic branching fractions of $b_{-} = (10.1 \pm 1.8 \pm 1.4) %$ for charged and $b_0=(10.9…

A Measurement of the Branching Fraction $B τ^{+} \to h^{-} π^{0} ν_{τ}$

The CLEO collaboration

Using data from the CLEO II detector at CESR, we measure $B (τ^{\pm} \to h^{\pm} π^{0} ν_{τ})$ where $h^{\pm}$ refers to either $π^{\pm}$ or $K^{\pm}$ . We use three different methods…

Measurement of Cabibbo Suppressed Decays of the $τ$ Lepton

The CLEO Collaboration

Branching ratios for the dominant Cabibbo-suppressed decays of the $τ$ lepton have been measured by CLEO~II in $e^{+} e^{-}$ annihilation at CESR ( $s \sim 10.6$ ~GeV) using kaons…

Precision Measurement of the $D_{s}^{*+} - D_{s}^{+}$ Mass Difference

The CLEO Collaboration

We have measured the vector-pseudoscalar mass splitting $M (D_{s}^{*+}) - M (D_{s}^{+}) = 144.22 \pm 0.47 \pm 0.37 M e V$ , significantly more precise than the previous world average. We minimize…
