Recent 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 of 6.9 fb at the Υ(4S) resonance and 2.3 fb at energies just below the BB̄ threshold. The origin of CP violation is one of the most important problems of experimental high energy physics. The study of B mesons has been attracting extensive world wide attention because it will allow for a decisive test of the quark-mixing sector in the Standard Model (SM). It is very important to test whether the SM provides the correct description of CP violation, in order to search for new physics beyond the SM. The analyses results described in this paper are mostly related to the CP violation study in beauty and charm meson decays. All simulated event samples were generated using GEANT-based simulation of the CLEO detector response.
