This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present measurements of the decays B[sup 0][yields] D[sub s][sup (*)+] D*[sup -], using data recorded by the BABAR detector in 1999 and 2000, consisting of 20.8 fb[sup -1]. The analysis is conducted with a partial reconstruction technique, in which only the D[sub s][sup (*)+] and the soft pion from the D*[sup -] decay are reconstructed. From the observed rates, we measure the branching fractions[Beta](B[sup 0][yields] D[sub s][sup+] D*[sup -])= (1.03[+-] 0.14[+-] 0.13[+-] 0.26)% and[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -])= (1.97[+-] 0.15[+-] 0.30[+-] 0.49)%, where the first error is statistical, the second is systematic, and the third is the error due to the D[sub s][sup+][yields][phi][pi][sup+] branching fraction uncertainty. From the[Beta](B[sup 0][yields] D*[sub s][sup+] D*[sup -]) angular distributions, we measure the fraction of longitudinal polarization[Lambda][sub L]/[Lambda]= (51.9[+-] 5.0[+-] 2.8)%, which is consistent with the theoretical prediction, based on factorization. These results are preliminary.

Book excerpt: The purpose of this analysis is the simultaneous measurement of the branching fraction, the longitudinal-polarization component, and the direct-CP-violating charge asymmetry for the B --> vector-vector decay mode B --> K*°?+, which has previously not been seen experimentally. The measurement of the polarization of the penguin decay is of special interest. There is no tree contribution to the decay amplitude and only a very small annihilation process.

This book was released on 2012 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report updated branching fraction measurements of the color-suppressed decays {bar B}° → D°?°, D*°?°, D°?, D*°?, D°?, D*°?, D°?', and D*°?'. We measure the branching fractions (x10−4):?({bar B}° → D°?°) = 2.69 ± 0.09 ± 0.13,?({bar B}° → D*°?°) = 3.05 ± 0.14 ± 0.28,?({bar B}° → D°?) = 2.53 ± 0.09 ± 0.11,?({bar B}° → D*°?) = 2.69 ± 0.14 ± 0.23,?({bar B}° → D°?) = 2.57 ± 0.11 ± 0.14,?({bar B}° → D*°?) = 4.55 ± 0.24 ± 0.39,?({bar B}° → D°?') = 1.48 ± 0.13 ± 0.07, and?({bar B}° → D*°?') = 1.49 ± 0.22 ± 0.15. We also present the first measurement of the longitudinal polarization fraction of the decay channel D*°?, f{sub L} = (66.5 ± 4.7 ± 1.5)%. In the above, the first uncertainty is statistical and the second is systematic. The results are based on a sample of (454 ± 5) x 106 B{bar B} pairs collected at the?(4S) resonance, with the BABAR detector at the PEP-II storage rings at SLAC. The measurements are the most precise determinations of these quantities from a single experiment. They are compared to theoretical predictions obtained by factorization, Soft Collinear Effective Theory (SCET) and perturbative QCD (pQCD). We find that the presence of final state interactions is favored and the measurements are in better agreement with SCET than with pQCD.

This book was released on 2011 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is threefold: Firstly, new measurements of both the exclusive and semi-inclusive partial decay widths of $B^{0}_{s} \to D^{(*)+}_{s}D^{(*)-}_{s}$ meson decays are presented. Secondly, the feasibility of extracting the unknown polarization components in $B^{0}_{s} \to D^{(*)+}_{s}D^{(*)-}_{s}$ by partial reconstruction of this pseudo-scalar to vector-vector decay in a Monte Carlo driven analysis scheme is studied. Finally, based on the suggestions contributed by the theory community this study discusses how a measurement of the branching fraction of semi-inclusive decays $B^{0}_{s} \to D^{(*)+}_{s}D^{(*)-}_{s}$ can contribute to gain insight about the relative decay width di erence in the B$0\atop{s}$--B$0\atop{s}$ meson system.

This book was released on 2009 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the B° → {bar ?}p?− branching fraction performed using the BABAR detector at the PEP-II asymmetric e+e− collider. Based on a sample of 467 x 106 B{bar B} pairs we measure ?(B° → {bar ?}p?−) [3.07 ± 0.31(stat.) ± 0.23(syst.)] x 10−6. The measured differential spectrum as a function of the dibaryon invariant mass m({bar ?}p) shows a near-threshold enhancement similar to that observed in other baryonic B decays. We study the {bar ?} polarization as a function of {bar ?} energy in the B° rest frame (E*{sub {bar ?}}) and compare it with theoretical expectations of fully longitudinally right-polarized {bar ?} at large E*{sub {bar ?}}.

This book was released on 2008 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study B° 2![rho]°[rho]° decays in a sample of 465 x 106 [Upsilon](4S) 2!B{bar B} events collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider located at the Stanford Linear Accelerator Center (SLAC).

The evidence for the B° 2![rho]°[rho]° signal has a significance of 3.1 standard deviations, including systematic uncertainties. We investigate the proper-time dependence of the longitudinal component in the decay and measure the CP-violating coefficients S{sub L}°° = (0.3 ± 0.7 ± 0.2) and C{sub L}°° = (0.2 ± 0.8 ± 0.3). They study the implication of these results for the unitarity triangle angle [alpha].
