چکیده
Based on a sample of approximately 500,000 hadronic Z 0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body exclusive charmless hadronic decays of B + , B 0 , and B 0 s mesons. The precise tracking capabilities of the SLD detector provided for the efficient reduction of combinatoric backgrounds, yielding the most precise available limits for ten of these modes.

متن کاملB Physics and Qcd at Sld
Analysis of B decays and QCD phenomena at the SLD experiment at the SLC ee collider is presented. The results are based on a sample of 150,000 hadronic Z decays collected between 1993 and 1995 together with 250,000 hadronic Z decays collected from 1996 to 1998 with an upgraded vertex detector. The large longitudinal polarization of the SLC e beam (average hPei 73%) was utilized by some of the m...
متن کاملCharmless Hadronic B Decays at BABAR
We present several searches for charmless hadronic two-body and three-body decays of B mesons from electron-positron annihilation data collected by the BABAR detector near the Υ (4S) resonance. We report the preliminary branching fractions B(B → ππ) = (4.1± 1.0± 0.7)× 10, B(B → Kπ) = (16.7 ± 1.6 ± 1.3) × 10, B(B → ρπ) = (49 ± 13 −5) × 10, B(B → ηK) = (62± 18± 8)× 10, and present upper limits fo...
متن کاملMeasurement of the B + and
The lifetimes of B + and B 0 mesons have been measured using a sample of 400,000 hadronic Z 0 decays collected by the SLD experiment at the SLC between 1993 and 1998. This inclusive topological measurement includes 250,000 hadronic Z 0 decays collected since 1996 with the SLD upgrade vertex detector. A high statistics sample of 30028 19636 charged neutral vertices with good charge purity is obt...
