Abstract:

The CLEO experiment at the CESR collider has used 13.7 fb(-1) of data to search for the production of the Omega(0)(c) (css ground state) in e(+)e(-) collisions at square root of (s) approximately 10.6 GeV. The modes used to study the Omega(0)(c) are Omega(-)pi(+), Omega(-)pi(+)pi(0), Xi-K-pi(+)pi(+), Xi0K-pi(+), and Omega(-)pi(+)pi(+)pi(-). We observe a signal of 40.4+/-9.0(stat) events at a mass of 2694.6+/-2.6(stat)+/-1.9(syst) MeV/c(2), for all modes combined.

CLEO III operation

NUCL INSTRUM METH A 462:1-2 (2001) 146-151

Authors:

G Viehhauser, CLEO III Collaboration

Abstract:

One year after the installation of most of the components of CLEO III, a strongly upgraded successor to the successful CLEO phase I and II experiments, and about half a year after its completion by the installation of the Silicon Detector, the experiment has successfully passed its commissioning phase and completed its first data-taking period. Major components of the detector upgrade are a new Drift Chamber with improved material distribution and a reduced volume to accommodate focussing accelerator components and the new particle identification system, a new four-layer Silicon Detector integrated in the overall tracking system to compensate for the reduced tracking volume and a proximity-focussing RICH with solid LiF crystal radiators and multi-wire proportional chambers filled with CH4/triethylamine. Preliminary performance benchmark studies have been completed and show that the CLEO III upgrade has been successful in achieving its design goals. (C) 2001 Published by Elsevier Science B.V.

Abstract:

We report results of a search for B-->tau(nu) in a sample of 9.7 x 10(6) charged B meson decays. We exclusively reconstruct the companion B decay to suppress background. We set an upper limit on the branching fraction B(B-->tau(nu))<8.4 x 10(-4) at 90% confidence level. We also establish B(B+/--->K+/-nu(nu))<2.4 x 10(-4) at 90% confidence level.

Search for B → τv and B → Kvv̄

Physical Review Letters 86:14 (2001) 2950-2954

Authors:

Abstract:

An analysis of 9.66 × 10⁶ charged B meson decays which results in a conservative upper limit on the branching fraction B(B → τν) < 8.4 × 10^-4. The analysis was slightly modified to establish B(B± → K± νν̄) < 2.4 × 10^-4. The method used is optimized for conditions available at Y(4S) experiments, and some application of the method to other rare decay modes with large missing energy was aniticipated.
