Book excerpt: We report an analysis of charmless hadronic decays of neutral B mesons to the final state K{sub S}°K{sup ±}[pi]{sup {-+}}, using a data sample of (465 ± 5) x 106 B{bar B} events collected with the BABAR detector at the [Upsilon](4S) resonance. We observe an excess of signal events with a significance of 5.2 standard deviations including systematic uncertainties and measure the branching fraction to be [Beta](B° → K{sub S}°K{sup ±}[pi]{sup {-+}}) = (3.2 {+-} 0.5 {+-} 0.3) x 10−6, where the uncertainties are statistical and systematic, respectively.
