Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of branching fractions and CP-violating asymmetries for neutral B meson decays to two-body final states of charged pions and kaons. The results are obtained from a data sample of about 88 million[Upsilon](4S)[yields] B[bar B] decays collected between 1999 and 2002 with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-independent fit we measure the charge-averaged branching fractions[Beta](B[sup 0][yields][pi][sup+][pi][sup -])= (4.7[+-] 0.6[+-] 0.2) x 10[sup -6] and[Beta](B[sup 0][yields] K[sup+][pi][sup -])= (17.9[+-] 0.9[+-] 0.7) x 10[sup -6], where the first uncertainty is statistical and the second is systematic; the 90% confidence level upper limit[Beta](B[sup 0][yields] K[sup+]K[sup -])

This book was released on 2012 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present improved measurements of CP-violation parameters in the decays B° →??−, B° → K+?−, and B° →?°?°, and of the branching fractions for B° →?°?° and B° → K°?°. The results are obtained with the full data set collected at the?(4S) resonance by the BABAR experiment at the PEP-II asymmetric-energy B factory at the SLAC National Accelerator Laboratory, corresponding to 467 ± 5 million B{bar B} pairs. We find the CP-violation parameter values and branching fractions S{sub?+?−} = -0.68 ± 0.10 ± 0.03, C{sub?+?−} = -0.25 ± 0.08 ± 0.02,?{sub K−?+} = -0.107 ± 0.016{sub -0.004}{sup +0.006}, C{sub?°?°} = -0.43 ± 0.26 ± 0.05,?(B° →?°?°) = (1.83 ± 0.21 ± 0.13) x 10−6,?(B° → K0?°) = (10.1 ± 0.6 ± 0.4) x 10−6, where in each case, the first uncertainties are statistical and the second are systematic. We observe CP violation with a significance of 6.7 standard deviations for B° →?+?− and 6.1 standard deviations for B° → K+{pi}{sup -}, including systematic uncertainties. Constraints on the Unitarity Triangle angle? are determined from the isospin relations among the B → {pi}{pi} rates and asymmetries. Considering only the solution preferred by the Standard Model, we find? to be in the range [71{sup o}, 109{sup o}] at the 68% confidence level.

This book was released on 2004 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present preliminary measurements of the branching fraction and the CP-violating charge asymmetry in the B --> K°?+ decay, and a preliminary measurement of the branching fraction of the B° --> K°{bar K}° decay. No evidence of direct CP violation in the B+ --> K°?+ mode is observed. The B° --> K°{bar K}° measurement constitutes the first observation of this decay channel: the probability of obtaining the result assuming the null-signal hypothesis is 3.4 x 10−6. The authors have also searched for the B+ --> {bar K}°K+ decay and set an upper limit on its branching fraction at 2.35 x 10−6 at the 90% C.L. The branching-fraction measurements reported here are consistent with previous measurements of the same quantities, but are extracted from a data sample larger by a factor of 2.6.
