Measurement of the Branching Fraction for the DecayB(caret)(backslash pm) to K (caret)(*backslash pm) gamma, K (caret) (*backslash pm) to K (caret) (backslash pm) backslash pi (caret) (0) with the BaBar Detector

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.
