Measurement of the branching ratios for the decays of Ds+ to ηπ+, η′π+, ηρ+, and η′ρ+

C. P. Jessop, K. Lingel, H. Marsiske, M. L. Perl et autres

Using a data sample with an integrated luminosity of $3.9{\mathrm{fb}}^{\mathrm{\ensuremath{-}}1}$ collected in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation with the CLEO-II detector at the Cornell Electron Storage Ring, we have measured the branching ratios for the decay modes ${D}_{s}^{+}\ensuremath{\rightarrow}(\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}){\ensuremath{\pi}}^{+}$ and ${D}_{s}^{+}\ensuremath{\rightarrow}(\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}){\ensuremath{\rho}}^{+}$ relative to ${D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\varphi}{\ensuremath{\pi}}^{+}.$ These decay …

Measurement of the branching fractions of Λc+→pK¯n(π)

M. S. Alam, S. B. Athar, Z. Ling, A. H. Mahmood et autres

Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon ${\ensuremath{\Lambda}}_{c}^{+}$ into ${\mathrm{pK}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0},$ $p{K}^{0},$ $p{K}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}},$ and $p{K}^{0}{\ensuremath{\pi}}^{0},$ all measured relative to ${\mathrm{pK}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}.$ The relative branching fractions are $0.67\ifmmode\pm\else\textpm\fi{}0.04\ifmmode\pm\else\textpm\fi{}0.11,0.46\ifmmode\pm\else\textpm\fi{}0.02\ifmmode\pm\else\textpm\fi{}0.04,0.52\ifmmode\pm\else\textpm\fi{}0.04\ifmmode\pm\else\textpm\fi{}0.05,$ …

New Measurement of B→D*π Branching Fractions

G. W. Brandenburg, Roy A. Briere, Y. S. Gao, D. Y.-J. Kim et autres

The decays $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$, followed by $B\ensuremath{\rightarrow}{D}^{*}\ensuremath{\pi}$ and ${D}^{*}\ensuremath{\rightarrow}D\ensuremath{\pi}$, permit reconstruction of all kinematic quantities that describe the sequence without reconstruction of the $D$, with reasonably low backgrounds. Using an integrated ${e}^{+}{e}^{\ensuremath{-}}$ luminosity of $3.1{\mathrm{fb}}^{\ensuremath{-}1}$ accumulated at the $\ensuremath{\Upsilon}(4S)$ by the CLEO-II detector, …

Measurement of the total cross section for e+e−→ hadrons at s=10.52 GeV

Romain Ould Ammar, P. Baringer, A. Bean, D. Besson et autres

Using the CLEO detector at the Cornell Electron Storage Ring, we have made a measurement of $R\ensuremath{\equiv}\ensuremath{\sigma}{(e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons})/\ensuremath{\sigma}{(e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})=3.56\ifmmode\pm\else\textpm\fi{}0.01\ifmmode\pm\else\textpm\fi{}0.07$ at $\sqrt{s}$=10.52 GeV. This implies a value for the strong coupling constant of ${\ensuremath{\alpha}}_{s}(10.52 \mathrm{GeV})=0.20\ifmmode\pm\else\textpm\fi{}0.01\ifmmode\pm\else\textpm\fi{}0.06$, or ${\ensuremath{\alpha}}_{s}{(M}_{Z})=0.13\ifmmode\pm\else\textpm\fi{}0.005\ifmmode\pm\else\textpm\fi{}0.03$.

Measurements of the meson-photon transition form factors of light pseudoscalar mesons at large momentum transfer

J. Gronberg, Theresa Schmaltz Hill, R. Kutschke, David J Lange et autres

Using the CLEO II detector, we have measured the differential cross sections for exclusive two-photon production of light pseudoscalar mesons ${\ensuremath{\pi}}^{0},$ \ensuremath{\eta}, and ${\ensuremath{\eta}}^{\ensuremath{'}}.$ From our measurements we have obtained the form factors associated with the electromagnetic transitions ${\ensuremath{\gamma}}^{*}\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\gamma}}\mathrm{meson}.$ We have measured …

Measurement of the Decay Amplitudes and Branching Fractions of B→J/ψK* and B→J/ψK Decays

C. Jessop, K. Lingel, H. Marsiske, M. L. Perl et autres

Using data taken with the CLEO II detector at the Cornell Electron Storage Ring, we present the first full angular analysis in the color-suppressed modes ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}$ and ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*+}$. This leads to a complete determination of the decay amplitudes of these modes including …
