Available in PDF, EPUB and Kindle. Book excerpt: We report a measurement of the B →?l? branching fraction based on 211 fb−1 of data collected with the BABAR detector. We use samples of B° and B mesons tagged by a second B meson reconstructed in a semileptonic or hadronic decay, and combine the results assuming isospin symmetry to obtain?(B° →?−l+?) = (1.33 ± 0.17{sub stat} ± 0.11{sub syst}) x 10−4. We determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element.
