The variety of phenomena occurring in the world surrounding us always has been stirring up curiosity of men. Based on empirical observations of nature and on experiments becoming more and more complex in the course of time, a variety of models concerning the structure of matter have been conceived. In this analysis Br[Bs→D$+\atop{s}$D$-\atop{s}$] is determined by measuring the relative branching fraction Br[Bs→D$+\atop{s}$D$-\atop{s}$]/Br[B0→D$+\atop{s}$D$-\atop{s}$].

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.

The authors present measurements of partial branching fractions of B 2!KX, B 2!K° X, and B 2![pi]+X, where X denotes any accessible final state above the endpoint for B decays to charmed mesons, specifically for momenta of the candidate hadron greater than 2.34 (2.36) GeV for kaons (pions) in the B rest frame. These measurements are sensitive to potential new-phisics particles which could enter the b 2!s(d) loop transitions. The analysis is performed on a data sample consisting of 383 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II e+e− asymmetric energy collider. The results are in agreement with standard model predictions and exclude large enhancements of the inclusive branching fraction due to sources of new physics.

We present the measurement of the ratios of branching fractions B(B ° -+ D-r +) to B(Bo -+ D--+), and B(B2 -+ OD-rr+rr - ) to B(Bo -- D-urx+r+-r- ). We analyze data taken with the CDF II detector that corresponds to an integrated luminosity of 355 pb - 1 in pp collisions at V = 1.96 TeV at the Fermilab Tevatron. Using a novel displaced track trigger we reconstruct 494 ± 28 B° -+ D;-r+ decays, 8098 + 114 BO -4 D-r + decays, 159 + 17 B° -+ D;-rr+7+rr- decays, and 3288 ± 76 Bo - D-rr++T77r- decays. Using the world average value of the B°-to-Bo production ratio fs/fd = 0.259 ± 0.038, we determine the ratios of branching fractions B(Bo -+ D-r +) -= 1.13 ± 0.08(stat.) ± 0.05(syst.) + 0.15(BR) ± 0.17(PR), B(Bo -+ D-rr+) B(Bo -+ D -rr+ r+rx- ) (= 1.01 ± 0.11(stat.) ± 0.06(syst.) ± 0.14(BR) B(Bo -+ D-7r-+r + + 0.15(PR), ri- ) where the uncertainties labeled BR and PR refer to the uncertainty on the D meson branching fractions and the production ratio fs fd, respectively.

The authors present preliminary measurements of branching fractions and charge asymmetries for the B meson decays B 2![eta]' K*, B 2![eta]'[rho], and B 2![eta]'[pi]. The data were recorded with the BABAR detector at PEP-II and correspond to 89 x 106 B{bar B} pairs produced in e+e− annihilation through the [Upsilon](4S) resonance. They find the branching fractions [Beta](B° 2![eta]K*°) = (19.0{sub -2.1}{sup +2.2} ± 1.3) x 10−6, [Beta](B+ 2![eta]K*+) = (25.7{sub -3.6}{sup +3.8} ± 1.8) x 10−6 with 90% confidence, and [Beta](B+ 2![eta]'[pi]+) = (2.8{sub -1.0}{sup +1.3} ± 0.3) x 10−6 (

The authors present measurements of branching fractions and charge asymmetries for the decays B 2![eta]K*, where K8 indicates a spin 0, 1, or 2 K [pi] system. The data sample corresponds to 344 x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider at SLAC. They measure the branching fractions (in units of 10−6): [Beta](B° 2![eta]K*°(892)) = 16.5 ± 1.1 ± 0.8, [Beta](B 2![eta]K*+(892)) = 18.9 ± 1.8 ± 1.3, [Beta](B° 2*0°) = 11.0 ± 1.6 ± 1.5, [Beta](B+ 20*+) = 18.2 ± 2.6 ± 2.6, [Beta](B° 2![eta]K*2°(1430)) = 9.6 ± 1.8 ± 1.1, and [Beta](B+ 2![eta]K*2+(1430)) = 9.1 ± 2.7 ± 1.4. They also determine the charge asymmetries for all decay modes.

We present the results of searches for B decays to charmless two-body final states containing [eta] or [omega] mesons, based on 20.7 fb−1 of data collected with the BABAR detector. We find the branching fractions [Beta](B 2![eta] K) = (70 ± 8 ± 5) x 10−6, [Beta](B° 2![eta] K°) = (42−11{sup +13} ± 4) x 10−6, and [Beta](B+ 2![omega][pi]+) = (6.6{sub -1.8}{sup +2.1} ± 0.7) x 10−6 where the first error quoted is statistical and the second systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are [Beta](B° 2![omega] K°)

We present results and prospects for searches for rare B and D meson decays with final state dimuons, including B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}, B{sub d}{sup 0} {yields} {mu}{sup +}{mu}{sup -}, and D{sup 0} {yields} {mu}{sup +}{mu}{sup -}. B0 Upper limits on the branching fractions are compared to previous CDF measurements, recent results from the B factories and theoretical expectations. We also report on new measurements of production and decay properties of the X(3872) particle, discovered in 2003 by the Belle Collaboration. New results on the measurement of the relative branching fraction for the Cabibbo suppressed decay B{sup +} {yields} J/{psi}{pi}{sup +} {Beta}(B{sup +} {yields} J/{psi}{pi}{sup +})/{Beta}(B{sup +} {yields} J/{psi}K{sup +}) are presented too. The presented results are based on the analyses of 70 to 220 pb{sup -1} of data collected by the CDF II detector in p{bar p} collisions at {radical}s = 1.96 GeV at Fermilab Tevatron.
