Available in PDF, EPUB and Kindle. Book excerpt: We present an analysis of the decays B° → K*°(892)? and B → K*+(892)? using a sample of about 383 million B{bar B} events collected with the BABAR detector at the PEP-II asymmetric energy B factory. We measure the branching fractions?(B° → K*°?) = (4.47 ± 0.10 ± 0.16) x 10−5 and?(B+ → K*+?) = (4.22 ± 0.14 ± 0.16) x 10−5. We constrain the direct CP asymmetry to be -0.033
