Measurement of the branching fraction for $Υ (1 S) \to τ^{+} τ^{-}$

D. Cinabro

We have studied the leptonic decay of the $Υ (1 S)$ resonance into tau pairs using the CLEO II detector. A clean sample of tau pair events is identified via events containing two cha…

Measurement of the B -> D^* l nu Branching Fractions and |Vcb|

The CLEO Collaboration

We study the exclusive semileptonic B meson decays B- -> D*0 l- nu and B0 -> D*+ l- nu using data collected with the CLEO II detector at CESR. We present measurements of the branch…

Production and Decay of D_1(2420)^0 and D_2^*(2460)^0

The CLEO Collaboration

We have investigated $D^{+} π^{-}$ and $D^{*+} π^{-}$ final states and observed the two established $L = 1$ charmed mesons, the $D_{1} (2420)^{0}$ with mass $242 1_{- 2 - 2}^{+ 1 + 2}$ MeV/c $^{2}$ …

A Measurement of $B (D_{s} \to ϕ l^{+} ν) / c a l B (D_{s} \to ϕ π^{+})$

The CLEO Collaboration

Using the CLEO~II detector at CESR, we have measured the ratio of branching fractions $B (D_{s}^{+} \to ϕ e^{+} ν) / B (D_{s}^{+} \to ϕ π^{+}) = 0.54 \pm 0.05 \pm 0.04$ . We use this meas…

Study of the Decay $Λ_c \to Λl^+ ν_{l}

The CLEO Collaboration

Using the CLEO II detector at CESR, we observe 500 $Λ l^{+}$ pairs consistent with the semileptonic decay $Λ_{c} \to Λ l^{+} ν_{l}$ . We measure $σ(e^+ e^- \to Λ_c X) \dot {cal B}(Λ_c^+ \to…
