Charmless 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 کاملCharmless Hadronic B Decays at BABAR
We present preliminary results of several searches for rare charmless hadronic decays of the B meson using data collected by the BABAR detector at the Stanford Linear Accelerator Center’s PEP-II storage ring. We search for the decays hh, hhh, hhπ, Xh, and XK S , where h = π or K, and X = η or ω. In a sample of 8.8 million BB decays we measure the branching fractions: B(B → ππ) = (9.3 −2.3 +1.2 ...
متن کاملMeasurement of Charmless Hadronic B Decays Branching Fraction at Babar
We present preliminary measurements of the branching fractions for charmless hadronic decays of B mesons into two-body final states with kaons, pions and a φ resonance. The measurements are based on a data sample of approximately 23 million BB̄ pairs collected by the BaBar detector at the PEP-II asymmetric B Factory at SLAC. Contributed to the Proceedings of the 36th Rencontres De Moriond On QCD...
متن کاملRare Hadronic and Radiative Penguin B Decays at BABAR
We report recent results in the study of rare hadronic and radiative penguin decays of B mesons. These results are based on a sample of 23 million BB pairs collected by the BABAR Collaboration at the SLAC PEP-II ee B Factory. Contributed to the Proceedings of the 5 KEK Topical Conference: Frontiers In Flavor Physics (KEKTC5), 20-22 Nov 2001, Tsukuba, Ibaraki, Japan. Stanford Linear Accelerator ...
