CLEO III, A Dectector To Measure Rare B Decays and CP Violation
نویسنده
چکیده
The symmetric ee collider CESR is undergoing a series of upgrades allowing for luminosities in excess of 2×10cms. The most important goals of the upgrade are precision measurement of standard model parameters Vcb, Vub, Vtd/Vts, fDs, and searching for CP violation and standard model violations in rare B decays. A new detector upgrade, called CLEO III, has started which includes a new silicon-wire drift chamber tracking system and a Ring Imaging Cherenkov Detector, RICH, using a LiF radiator and CH4-TEA gas based photon detector. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Charm Physics Results from CLEO The CLEO Collaboration
We present recent results in the charm sector from the CLEO Collaboration. The data used were collected by the CLEO II and III detectors at the Cornell Electron Storage Ring (CESR). Measurements of form factors and branching fractions in semileptonic decays of D-meson and charmed-baryons, searches for CP violation and rare decays, and Dalitz analyses of D-meson decays are discussed, as well as ...
متن کاملStudies of B 0 Decays for Measuring Sin2
Future asymmetric ee ! (4S) B factories are being constructed to search for CP violation in B decays. It is hoped that a CP asymmetry may be observed in B{B 0 mixing in analogy with that found in neutral kaons. In this mixing measurement, B decays to CP eigenstates, such as the rare decay B ! KS, may provide information on the CKM angle sin(2 ). I discuss decay additional CP eigenstate branchin...
متن کاملCurrent Issues in CP Violation
A brief review of CP violation in K and B decays is given. While the observables ε and Re(ε/ε) describing CP violation in neutral K decays do not allow a powerful test of the CKM mechanism of CP violation, rare K → πνν decays and in particular the B-meson system are much more promising in this respect. After a brief look at the K system, selected aspects of CP-violating effects in B decays are ...

متن کاملRecent Results from CLEO Collaboration
The Cornell Electron Storage Ring (CESR) is a symmetric ee collider operating at the Υ(4S) resonance. The CLEO II and II.V detector configurations are described in detail elsewhere. The integrated luminosity of the full CLEO II+II.V data is 9.2 fb at the Υ(4S) resonance, which corresponds to about 9.7 × 10 BB̄ pairs, and 4.6 fb at energies just below the BB̄ threshold. The CLEO III data consists ...
