Search for Direct CP Violation in B to K pi, pi pi, K K, Quasi-Two-Body B Decays and B to Kstar gamma with the BABAR Detector at the PEP-II Collider

Abstract

A sample of 23 million B{bar B} events collected with the BABAR detector at the PEP-II collider is used in a search for direct CP violation in charmless two-body B decays, quasi two-body B decays, and the radiative penguin decays B {yields} K*{gamma}. No evidence for direct CP violation is found in the considered modes and 90% confidence level limits are reported. We also present a limit on the branching fraction of the decay B{sup 0} {yields} {gamma}{gamma}.
