The authors report a Dalitz-plot analysis of the charmless hadronic decays of neutral B mesons to K{sup ±}?{sup {-+}}?°. With a sample of (231.8 ± 2.6) x 106?(4S) → B{bar B} decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, they measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B° and {bar B}° decays and determine the corresponding CP-averaged branching fractions and charge asymmetries. The inclusive branching fraction and CP-violating charge asymmetry are measured to be?(B° → K?−?°) = (35.7{sub -1.5}{sup +2.6} ± 2.2) x 10−6, and?{sub CP} = -0.030{sub -0.051}{sup +0.045} ± 0.055 where the first errors are statistical and the second systematic. They observe the decay B° → K*°(892)?° with the branching fraction?(B° → K*°(892)?°) = (3.6{sub -0.8}{sup +0.7} ± 0.4) x 10−6. This measurement differs from zero by 5.6 standard deviations (including the systematic uncertainties). The selected sample also contains B° → {bar D}°?° decays where {bar D}° → K+?−, and they measure?(B° → {bar D}°?°) = (2.93 ± 0.17 {+-} 0.18) x 10−4.
Results are reported from a Dalitz plot analysis of 17750 K°/sub e3/ candidates obtained in an experiment designed to study both the semileptonic and 3.pi. decay modes of the K°/sub L/ with high efficiency across the Dalitz plot.
