Book Description
Ds mesons are fully reconstructed from four final states using approximately 229fb-1 of data delivered by the PEP-II e+e- collider and collected by the BaBar experiment at the Stanford Linear Accelerator Centre during the period 1999 to 2004. Measurements of the exclusive branching fractions (average over charge-conjugate decays), B, of the decays D+s → K+[pi]0, D+s→ [pi]+K0 and D+s → [pi]+[pi]0 relative to the reference mode D+s → K+$\bar{K}$0 are presented.

Book Description
The authors report on the evidence for the decays B° → D{sub s}?− and B° → D{sub s}− K+ and the results of a search for the decays B° → D*{sub s}+?− and B° → D*{sub s}− K+ from a sample of 84 million?(4S) decays into B meson pairs collected with the BaBar detector at the PEP II asymmetric-energy e+e− collider. The measured B° → D{sub s}+?− yield has a probability of less than 10−3 to be a fluctuation of the background and they measure the branching fraction?(B° → D{sub s}+?−) = (3.2 ± 0.9(stat.) ± 1.0 (syst.)) x 10−5. The measured B° → D{sub s}− K+ yield has a probability of less than 5 x 10−4 to be a fluctuation of the background and they measure the branching fraction?(B° → D{sub s}− K+) = (3.2 ± 1.0(stat.) ± 1.0(syst.)) x 10−5. They also set 90% C.L. limits?(B° → D*{sub s}+?−)

Book Description
We present results from BaBar experiment for the measurement of inclusive and exclusive branching fractions of B mesons into final states containing J/[psi], [psi](2S) and[chi]c. The contributions of CP even and odd amplitudes in the decay B[sup 0][yields] J/[psi]K*[sup 0] are determined from an angular analysis. We report the measurements of the branching ratios B[sup 0][yields] D*[sup+] D*[sup -] and D*[sup+] D*[sup -] K[sub S][sup 0], and the study of exclusive two-body and quasi-two-body charmless decays. The branching fraction of the decay B[sup 0][yields] K*[sup 0][gamma] has been determined and the corresponding CP asymmetry has been measured.

Book Description
The study of rare hadronic B decays at LHCb and at the planned Super-B factories is a valueable tool in the search for new physics. The variety of hadronic decay channels allows for over-constraining measurements of flavour-changing neutral currents. The author discusses several aspects of new physics in rare hadronic B decays. In the first part of the book, the Minimal Supersymmetric Standard Model (MSSM) with Minimal Flavor Violation is analysed. In this model, large effects can occur in rare B decays due to tan(beta)-enhanced corrections which have to be resummed to all orders. The known resummation formulae are generalised beyond the decoupling limit and novel effects in couplings involving genuine supersymmetric particles are studied. In the second part of the book, the possibility of probing new physics in electroweak penguins via hadronic B decays is discussed. Such kind of new physics is suggested by puzzling data in B K, pi decays. The author shows that a measurement of the purely isospin-violating decays Bs phi, pi(rho) could shed light on this puzzle. A model-independent study and a study of concrete well-motivated new physics scenarios are performed.
