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.

The authors present preliminary results on the Dalitz plot analysis of B° --> K?−?° decays. The data sample comprises 213 million?(4S) --> B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. They report measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892)+?− and?(770)−K+. Observations of B° decays to the K?S-wave intermediate states, K0*(1430)+?− and K0*(1430)°?°, are reported. Evidence of the decay B° --> K*(892)°?° is seen. They set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.

Results for the first measurement of the inclusive branching and CP asymmetry of the charmless 3-body decay B+ → K+[pi]0[pi]0 are presented. The analysis uses a data sample with an integrated luminosity of 429.0 fb-1, recorded by the BABAR detector at the PEP-II asymmetric B Factory. This sample corresponds to 470.9 ±} 2.8 million B$\bar{B}$ pairs. Measurements of the branching fractions (B) and CP asymmetries (ACP) of some of the intermediate resonances in the K+[pi]0[pi]0 Dalitz plot are also presented.

Particle physicists study the smallest particles and most basic rules of their interactions in humankind's current scope. The Charm Analysis Working Group (CWG) of the BaBar Collaboration studies decays involving the charm quark. They currently study mixing in D decays, an interesting and poorly understood phenomenon in current physics models. We, as part of the CWG, investigated the plausibility of using Dalitz plots and the BaBar analysis framework to study mixing in Wrong Sign (WS) D[sup 0][yields] K[pi][pi][sup 0] decays. Others in the CWG have studied mixing in the 2-body decay, D[sup 0][yields] K[pi]. The 3-body decay analyzed with the RooFitDalitz analysis package and Dalitz plots provides more information and another way of separating Doubly Cabibbo Suppressed Decays (DCSD) from mixing--which share the same end products. Through doing many simulations, we have demonstrated the usefulness of this approach. We selected D[sup 0][yields] K[pi][pi][sup 0] events from Simulation Production run No. 4 (SP4) and BaBar's run 1 and run 2. We made Dalitz plots with this data. Now that we better understand Dalitz plots and software, we plan to select WS D[sup 0][yields] K[pi][pi][sup 0] events and perform rate fits as discussed in BaBar Analysis Document (BAD) No. 443, as well as fits for several different decay times and resonances, in order to further distinguish DCSD from mixing.

This thesis describes a Dalitz plot analysis of B{sup 0} {yields} K{sup +}{pi}{sup -}{pi}{sup 0} decays. The data sample comprises 213 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator Center in California (SLAC). Preliminary results are presented for measurements of the inclusive branching fraction, quasi-two-body fractions and CP-violating charge asymmetries for intermediate states including K*(892){sup +}{pi}{sup -} and {rho}(770){sup -}K{sup +}. Observations of B{sup 0} decays to the K{pi} S-wave intermediate states, K*{sub 0}(1430){sup +}{pi}{sup -} and K*{sub 0}(1430){sup 0}{pi}{sup 0}, are reported. Evidence of the decay B{sup 0} {yields} K*(892){sup 0}{pi}{sup 0} is seen. We set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.
