Measurement Of The B Rho Pi0 Branching Fraction And Direct Cp Asymmetry written by J. C. Chen and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2005 with categories.
An improved measurement of the process B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0} is presented. The data sample of 211 fb{sup -1} comprises 232 million {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are calculated using an extended maximum likelihood fitting method. The branching fraction and asymmetry are found to be {Beta}(B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0}) = [10.0 {+-} 1.4 (Stat.) {+-} 0.9 (Syst.)] x 10{sup -6} and {Alpha}{sub CP}(B{sup {+-}} {yields} {rho}{sup {+-}}{pi}{sup 0}) = -0.01 {+-} 0.13 (Stat.) {+-} 0.02 (Syst.), superseding previous measurements. The statistical significance of the signal is calculated to be 8.7{sigma}.

The authors present improved measurements of the branching fraction and CP asymmetry for the process B{sup ±} → [rho]{sup ±}[pi]°. The data sample corresponding to 211 fb−1 comprises 232 million [Upsilon](4S) → B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are measured using an extended maximum likelihood fitting method. The branching fraction and Cp asymmetry are found to be [Beta](B{sup ±} → [rho]{sup ±}[pi]°) = [10.2 {+-} 1.4(stat) {+-} 0.9(syst)] x 10−6 and [Alpha]{sub CP}(B{sup {+-}} → [rho]{sup {+-}}[pi]°) = -0.01 {+-} 0.13(stat) {+-} 0.02(syst).
