【 摘 要 】

The branching fraction of the radiative penguin B meson decay B{sup {+-}} {yields} K*{sup {+-}}{gamma} is measured at the PEP-II asymmetric energy e{sup +}e{sup -} collider, operating at a center of momentum energy of 10.58 GeV, the {Upsilon}(4S) resonance. This document concentrates on the case K*{sup {+-}} {yields} K{sup {+-}}{pi}{sup 0}; {pi}{sup 0} {yields} {gamma}{gamma}. This analysis is based on a dataset of 88.2-million {Upsilon}(4S) {yields} B{bar B} events corresponding to 81.3 fb{sup -1} collected with the BABAR detector.
