Available in PDF, EPUB and Kindle. Book excerpt: The branching fractions of the decays B° → K*°? and B → K*+? are measured using a sample of 88 x 106 B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy e+e− collider. They find?(B° → K*°?) = (3.92 ± 0.20(stat.) ± 0.24(syst.)) x 10−5,? (B+ → K*+?) = (3.87 ± 0.28(stat.) ± 0.26(syst.)) x 10−5. The measurements also constrain the direct CP asymmetry to be -0.074
