Search for B --> tau(nu) and B --> K(nu)nu.
Phys Rev Lett 86:14 (2001) 2950-2954
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

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.The CLEO III ring imaging Cherenkov detector

Abstract:
The CLEO detector has been upgraded to include a state of the art particle identification system, based on the Ring Imaging Cherenkov detector (RICH) technology, in order to take data at the upgraded CESR electron positron collider. The expected performance as well as the preliminary results are reviewed from an engineering run during the first few months of operation of the CLEO III detector. © 2001 Elsevier Science B.V.The CLEO III ring imaging Cherenkov detector
