A sample of 23 million BB events collected with the BABAR detector at the PEP-II collider is used in a search for direct CP violation in charmless two-body B decays, quasi two-body B decays, and the radiative penguin decays B → K∗γ. No evidence for direct CP violation is found in the considered modes and 90% confidence level limits are reported. We also present a limit on the branching fraction...

background: although lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. objective: to assess the association between exposure to outdoor air pollution and chronic bronchitis in lebanon. methods: a pilot case-control study was conducted in two tertiary care hospitals....

Charmless semileptonic decays, B → X u ℓ¯ ν, are studied in a sample of 232 million BB decays recorded with the BABAR detector, in events where the decay of the second B meson is fully reconstructed. Inclusive charmless decays are selected in kinematic regions where the dominant background from semileptonic B decays to charm is reduced by requirements on the hadronic mass M X and the momentum t...
