Book excerpt: We present a search for decays of B mesons to final states with a b1 meson and a [rho] or K*(892) meson. The search is based on a data sample consisting of 465 million B{bar B} pairs collected by the BABAR detector at the SLAC National Accelerator Laboratory. We do not observe any statistically significant signal. The upper limits we set on the branching fractions range from 1.4 to 8.0 x 10−6 at the 90% confidence level (C.L.), including systematic uncertainties.

Available in PDF, EPUB and Kindle. Book excerpt: We present the results of searches for B decays to charmless final states involving?, f0(980), and charged or neutral? mesons. The data sample corresponds to 384 x 106 B{bar B} pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy ee− collider at SLAC. We find no significant signals and determine the following 90% confidence level upper limits on the branching fractions, including systematic uncertainties:?(B° →??)
