This book was released on 2010 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary goals of the BABAR experiment are the detection of CP violation (CPV) in the B meson system, the precise measurement of some of the elements of the CKM matrix and the measurement of the rates of rare B meson decays. At present, BABAR has achieved major successes: (1) the discovery, in neutral B decays, of direct and mixing-induced CP violation; (2) accurate measurements of the magnitudes of the CKM matrix elements.

Available in PDF, EPUB and Kindle. Book excerpt: We present a study of the decay B− 2!D{sub (CP)}° K− and its charge conjugate, where D{sub (CP)}° is reconstructed in CP-even, CP-odd, and non-CP flavor eigenstates, based on a sample of 232 million [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the PEP-II ee− storage ring. We measure the partial-rate charge asymmetries AC{sub CP±} and the ratios R{sub CP±} of the B 2!D° K decay branching fractions as measured in CP± and non-CP D° decays: A{sub CP+} = 0.35 ± 0.13(stat) ± 0.04(syst), A{sub CP-} = -0.06 ± 0.13(stat) ± 0.04(syst), R{sub CP+} = 0.90 ± 0.12(stat) ± 0.04(syst), R{sub CP-} = 0.86 {+-} 0.10(stat) {+-} 0.05(syst).

This book was released on 2008 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report a study of B{sup ±} 2!D*K{sup ±} decays with D* decaying to D[pi]° or D[gamma], using 383 x 106 B{bar B} pairs collected at the [Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II B-Factory. The D meson decays under study include a non-CP mode (K{sup ±}[pi]{sup {-+}}), CP-even modes (K{sup ±}K{sup {-+}}, [pi]{sup ±}[pi]{sup {-+}}) and CP-odd modes (K{sub S}°[pi]°, K{sub S}°[phi], K{sub S}°[omega]). They measure ratios (R*{sub CP±}) of branching fractions of decays to CP eigenmode states and to flavor-specific states as well as CP asymmetries A*{sub CP±} = -0.11 ± 0.09 ± 0.01, R*{sub CP+} = 1.31 ± 0.13 ± 0.04, and A*{sub CP-} = 0.06 ± 0.10 {+-} 0.02, R*{sub CP-} = 1.10 {+-} 0.12 {+-} 0.04, where the first error is statistical and the second error is systematic. Translating the results into an alternative parameterization, widely used for related measurements, they obtain x*+ = 0.11 {+-} 0.06 {+-} 0.02 and x* = 0.00 {+-} 0.06 {+-} 0.01. No significant CP-violating charge asymmetry is found in either the flavor-specific mode D 2!K{sup {+-}}[pi]{sup {-+}} or in B{sup {+-}} 2!D*[pi]{sup {+-}} decays.

This book was released on 2003 with total page pages. 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.

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 2003 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors present measurements of the branching fraction and CP-violating asymmetries for neutral B decays to D*{sup ±} D{sup {-+}}. The measurement uses a data sample for approximately 88 million [Upsilon](4S) 2!B{bar B} decays collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. They measure the branching fraction to be (8.8 ± 1.0 ± 1.3) x 10−4 and the time-integrated CP-violating asymmetry between the rates to D*− D and D* D− to be [Alpha] = -0.03 ± 0.11 ± 0.05. They also measure the time-dependent CP-violating asymmetry parameters to be S{sub -+} = -0.24 ± 0.69 ± 0.12, C{sub -+} = -0.22 ± 0.37 ± 0.10 for B 2!D*− D+ and S{sub +-} = -0.82 ± 0.75 ± 0.14, C{sub +-} = -0.47 ± 0.40 {+-} 0.12 for B 2!D*+ D−. In each case the first error is statistical and the second error is systematic.
