Book Description
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 -])

Book Description
The authors present preliminary results of improved measurements of the CP-violating asymmetries and branching fractions in the decays B° →??−, B° → K+?−, B° →?°?°, and B° → K°?°. This update includes all data taken at the?(4S) resonance by the BABAR experiment at the asymmetric PEP-II B-meson factory at SLAC, corresponding to 467 ± 5 million B{bar B} pairs. They find S{sub??} = -0.68 ± 0.10 ± 0.03, C{sub??} = -0.25 ± 0.08 ± 0.02,?{sub K{sub?}} = -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° → K°?°) = (10.1 ± 0.6 ± 0.4) x 10−6, where the first error is statistical and the second is systematic. They observe CP violation with a significance of 6.7? in B° → {pi}− and 6.1? in B° → K+{pi}−. Constraints on the Unitarity Triangle angle? are determined from the isospin relation between all B → {pi}{pi} rates and asymmetries.

Book Description
The authors present preliminary measurements of the Cp asymmetries and branching fractions for B {yields} {pi}{pi} and B {yields} K{pi} decays. A total of 347 million B{bar B} events collected by the BABAR detector at the PEP-II asymmetric-energy e{sup +}e{sup -} collider at SLAC are used for these results.

ISBN: 9812704264
Category : Science
Languages : en
Pages : 551

Book Description
This book provides an update on our understanding of strong interaction, with theoretical and experimental highlights included. It is divided into five sections. The first section is devoted to the investigations into and the latest results on the mechanism of quark confinement. The second and third sections focus respectively on light and heavy quarks (effective field theories, SchwingerOCoDyson approach and lattice QCD results). The fourth section deals with the deconfinement mechanism and quarkOCogluon plasma formation signals. The last section presents highlights of experiments, new physics beyond QCD, and nonperturbative approaches in other theories (strings and SUSY) that may be useful in QCD."

Book Description
Based on a sample of 227 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the branching fraction?(B° →?°?°) = (1.17 ± 0.32 ± 0.10) x 10−6, and the asymmetry C{sub?°?°} = -0.12 ± 0.56 ± 0.06. The B° →?°?° signal has a significance of 5.0?. We also measure?(B →?+?°) = (5.8 ± 0.6 ± 0.4) x 10−6,?(B+ → K+?°) = (12.0 ± 0.7 ± 0.6) x 10−6, and the charge asymmetries?{sub?+{pi}°} = -0.01 ± 0.10 ± 0.02 and?{sub K{sup +}{pi}°} = 0.06 ± 0.06 ± 0.01. Using isospin relations we find an upper bound on the angle difference.
