Book Description
Using 1.3 fb-̂1 of data from p-pbar collisions at sqrt{s}=1.96 TeV collected with the CDF II detector at the Fermilab Tevatron, we have measured the relative branching ratio BR(B-̂ -> D0̂ K-̂)/BR(B-̂ -> D0̂ pi-̂) and its charge conjugate in the D0̂ flavor decay mode D0̂_f -> K-̂pi+̂ and the CP-even decay modes D0̂ -> K-̂K+̂ and D0̂ -> pi-̂pi+̂. From these measurements, we derive: R = (7.99 +- 0.33(stat.) +- 0.38(sys.)) %, R_{CP+} = 1.15 +- 0.17(stat.) +- 0.02(sys.), A_{CP+} = 0.10 +- 0.15(stat.) +- 0.02(sys.). These values are consistent with Standard Model expectations.

Book Description
The authors present a measurement of R{sub B}, the ratio of the branching fraction for the rare decay D° → K?− to that for the Cabibbo-favored decay D° → K−?+. Charge conjugate decays are implicitly included. A signal of 2005 ± 104 events for the decay D° → K+?− is obtained using the CDF II detector at the Fermilab Tevatron collider. The data set corresponds to an integrated luminosity of 0.35 fb−1 produced in {bar p}p collisions at √s = 1.96 TeV. Assuming no mixing, they find R{sub B} = [4.05 ± 0.21(stat) ± 0.11(syst)] x 10−3. This measurement is consistent with the world average, and comparable in accuracy with the best measurements from other experiments.

Book Description
In this thesis, we performed a study for the decay modes D+ → + K-K+K+ and D+s → + K-K+K+, using the data collected by the E791, a hadroproduction of charm experiment at Fermilab. The D+ → + K-K+K+ decay is doubly Cabibbo suppressed while the D+s → + K-K+K+ decay is singly Cabibbo suppressed. We found 11.6 +- 3.9 events in the D+ mass region and 8.9 +- 3.3 in the D+s mass region. The D+ → + K-K+K+ branching ratio is measured to be (3.7 +- 1.3 +- 0.6) x 10-4 while the D+ → + K-K+K+ branching ratio relative to D+s → + K-K+K+ is measured to be (4.2 +- 1.5 +- 0.6) x 10-2.

Book Description
The branching ratio for the decay mode D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu] has been measured with two methods. The first uses D[sup 0] [yields] [bar K] [sup [minus]][mu][sup +][nu] for normalization, and yields the result B(D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu] = (3.25 [plus minus] 0.71 [plus minus] 0.75)%. From this method we also obtain the direct measurement [Gamma](D[sup +] [yields][bar K]*[sup 0][mu][sup +] [nu]/[Gamma](D[sup 0] [yields] K[sup [minus]] [mu][sup +] [nu]) = 0.43 [plus minus] 0.09 [plus minus] 0.09. The second method uses the mode D[sup +] [yields] K[sup [minus]][pi][sup +] [pi][sup +] for normalization and yields B(D[sup +] [yields] [bar K]*[sup 0] [mu][sup +][nu]) = 4.18 [plus minus] 0.66 [plus minus]0.96)%. Combining the results of the two methods yields B(D[sup +] [yields] [bar K]*[sup 0][mu][sup +][nu]) = 3.57 [plus minus] 0.96)%.

Book Description
The authors measure the absolute branching fraction for D° → K−? using partial reconstruction of {bar B}° → D*+Xl−{bar {nu}}{sub {ell}} decays, in which only the charged lepton and the pion from the decay D*+ → D°?+ are used. Based on a data sample of 230 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, they obtain?(D° → K−?+) = (4.007 ± 0.037 ± 0.070)%, where the first error is statistical and the second error is systematic.

Book Description
I present measurements of the relative branching ratios, Dalitz plot structures and CP-asymmetry values in the three-body singly Cabibbo-suppressed decays D0 ->pi-pi+pi0 and D0 ->K-K+pi0 using data collected by the BaBar detector at the PEP-II asymmetric-energy ring at SLAC. I apply the results of the D0 ->pi-pi+pi0 analysis to extracting CP-violation parameters related to the CKM angle gamma (or phi_3) using the decay B- -> D0[->pi-pi+pi0] K-

Book Description
We present a measurement of the absolute branching fraction for D° → K−? using the reconstruction of the decay chain {bar B} → D*+Xl−{bar {nu}}, D*+ → D°?+ where only the lepton and the low-momentum pion from the D*+ are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined Br(D° → K−?+) = [3.81 ± 0.15(stat.) ± 0.16(syst.)]%.
