Anti-Search for the Glueball Candidate f_J(2220) in Two-Photon Interactions

K. Benslama, CLEO Collaboration

Using 13.3 fb^{-1} of e^+e^- data recorded with the CLEO II and CLEO II.V detector configurations at CESR, we have searched for f_J(2220) decays to K^0_{S} K^0_{S} in untagged two-…

Study of $B \to ψ (2 S) K$ and $B \to ψ (2 S) K^{*}$ (892) Decays

S. Richichi, CLEO Collaboration

Color-suppressed decays of $B$ mesons to final states with $ψ (2 S)$ mesons have been observed with the CLEO detector. The branching fractions for the decays $B^{+} \to ψ (2 S) K^{+}$ , $B^…

Search for Decays of B^{0} Mesons into Pairs of Leptons: B{0} -> e^{+}e^{-}, B^{0} -> μ^{+}μ^{-} and B^{0} -> e^{\pm}μ^{\mp}

T. Bergfeld, CLEO Collaboration

We search for the decays of the $B^{0}$ meson into $e^{+} e^{-}$ , $μ^{+} μ^{-}$ $e^{\pm} μ^{\mp}$ pairs in a sample of $9.7 \times 1 0^{6}$ $B B ˉ$ pairs recorded by CLEO detector. No signal is…

Study of B Decays to Charmonium States $B \to η_{c} K$ and $B \to χ_{C 0} K$

K. W. Edwards, CLEO Collaboration

In a sample of $9.66 \times 1 0^{6} B B ˉ$ pairs collected with the CLEO detector we make the first observation of B decays to an $η_{c}$ and a kaon. We measure branching fractions $B…

Measurement of the Relative Branching Fraction of $Υ (4 S)$ to Charged and Neutral B-Meson Pairs

J. P. Alexander, CLEO Collaboration

We analyze 9.7 x 10^6 B\bar{B}$ pairs recorded with the CLEO detector to determine the production ratio of charged to neutral B-meson pairs produced at the Y(4S) resonance. We meas…

Measurements of the Mass, total Width and Two-Photon Partila Width of the $η_{c}$ Meson

G. Brandenburg, CLEO Collaboration

Using 13.4 $f b^{- 1}$ of data collected with the CLEO detector at the Cornell Electron Storage Ring, we have observed 300 events for the two-photon production of ground-state pseudo…
