Available in PDF, EPUB and Kindle. Book excerpt: The branching fractions of the exclusive decays B[sup 0][yields] K*[sup 0][gamma] and B[sup+][yields] K*[sup+][gamma] are measured. from a sample of (22.74[+-] 0.36) x 10[sup 6] B[bar B] decays collected with the BABAR detector at the PEP II asymmetric e[sup+]e[sup -] collider. We find[Beta](B[sup 0][yields] K*[sup 0][gamma])= (4.23[+-] 0.40(stat.)[+-] 0.22(sys.)) x 10[sup -5], [Beta](B[sup+][yields] K*[sup+][gamma])= (3.83[+-] 0.62(stat.)[+-] 0.22(sys.)) x 10[sup -5] and constrain the CP-violating charge asymmetry to be -0.170
