The authors present preliminary results on the Dalitz plot analysis of B[sup 0] --> K[sup +][pi][sup -][pi][sup 0] decays. The data sample comprises 213 million [Upsilon](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)[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] --> K*(892)[sup 0][pi][sup 0] is seen. They set upper limits at 90% confidence level on branching fractions of the nonresonant and other less significant intermediate states.

Measurement Of Cp Violation Parameters With A Dalitz Plot Analysis Of B To D Pi Pi Pi0 K written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2007 with categories.

We report the results of a CP violation analysis of the decay B{sup {+-}} → D{sub??−?°}K{sup {+-}}, where D{sub?+?−?°} indicates a neutral D meson detected in the final state?+?−?°, excluding K{sub S}°?°. The analysis makes use of 324 million e+e− → B{bar B} events recorded by the BABAR experiment at the PEP-II e+e− storage ring. By analyzing the?+?−?° Dalitz plot distribution and the B{sup {+-}} → D{sub?+?−?°} K{sup {+-}} branching fraction and decay rate asymmetry, we calculate parameters related to the phase? of the CKM unitarity triangle. We also measure the magnitudes and phases of the components of the D° → {pi}+{pi}−{pi}° decay amplitude.

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.

I present measurements of the relative branching ratios, Dalitz plot structures and CP-asymmetry values in the three-body singly Cabibbo-suppressed decays D0 ->pi-pi+pi0 and D0 ->K-K+pi0 using data collected by the BaBar detector at the PEP-II asymmetric-energy ring at SLAC. I apply the results of the D0 ->pi-pi+pi0 analysis to extracting CP-violation parameters related to the CKM angle gamma (or phi_3) using the decay B- -> D0[->pi-pi+pi0] K-
