[A Case of Transverse Colon Cancer in Which Long-Term Chemotherapy Was Performed after Palliative Colonic Stent Placement].

Masami Ueda, Masakazu Ikenaga, Katsuya Ohta, Yoshinao Chinen et autres

We report a case involving a 76-year-old woman with transverse colon cancer undergoing long-term chemotherapy following palliative colonic stent placement. She visited our hospital with a diagnosis of colonic obstruction. Her abdomen was evidently distended and tender. CT revealed the apple core …

The originally published correlation coefficients between measured branching ratios are incorrect.

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 …

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 …

Limit on the Two-Photon Production of the Glueball Candidate fJ(2220) at the Cornell Electron Storage Ring

R. Godang, K. Kinoshita, I. C. Lai, P. Pomianowski et autres

We use the CLEO detector at the Cornell ${e}^{+}{e}^{\ensuremath{-}}$ storage ring, CESR, to search for the two-photon production of the glueball candidate ${f}_{J}(2220)$ in its decay to ${K}_{s}{K}_{s}$. We present a restrictive upper limit on the product of the two-photon partial width …

First Observation of Inclusive B Decays to the Charmed Strange Baryons Ξc0 and Ξc+

Barry C. Barish, M. Chadha, S. Chan, G. Eigen et autres

Using data collected in the region of the $\ensuremath{\Upsilon}(4S)$ resonance with the CLEO II detector operating at the Cornell Electron Storage Ring (CESR), we present the first observation of $B$ mesons decaying into the charmed strange baryons ${\ensuremath{\Xi}}_{c}^{0}$ and ${\ensuremath{\Xi}}_{c}^{+}$. We find …

New upper limit on the decay η→e+e−

Thomas E. Browder, Fengjun Li, Yu-Xiang Li, Jorge L. Rodriguez et autres

We have searched for the rare decay of the $\ensuremath{\eta}$ meson $\ensuremath{\eta}\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}$ using the CLEO II detector. The $\ensuremath{\eta}$'s were produced in ${e}^{+}{e}^{\ensuremath{-}}$ collisions with 10 GeV center-of-mass energy at the Cornell Electron Storage Ring (CESR). We find with $90%$ confidence the …

Determination of the Michel parameters and the τ neutrino helicity in τ decay

J. P. Alexander, Chris J. Bebek, B. E. Berger, Karl Berkelman et autres

Using the CLEO II detector at the Cornell Electron Storage Ring operated at $\sqrt{s}=10.6\mathrm{GeV},$ we have determined the Michel parameters \ensuremath{\rho}, \ensuremath{\xi}, and \ensuremath{\delta} in ${\ensuremath{\tau}}^{\ensuremath{\mp}}\ensuremath{\rightarrow}{l}^{\ensuremath{\mp}}\ensuremath{\nu}\overline{\ensuremath{\nu}}$ decay as well as the \ensuremath{\tau} neutrino helicity parameter ${h}_{{\ensuremath{\nu}}_{\ensuremath{\tau}}}$ in ${\ensuremath{\tau}}^{\ensuremath{\mp}}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{\mp}}{\ensuremath{\pi}}^{0}\ensuremath{\nu}$ decay.
