The authors present measurements of the relative branching ratios, Dalitz plot structures and CP-asymmetry values in the three-body singly Cabibbo-suppressed decays D° →?−??° and D° → K−K+?° using data collected by the BABAR detector at the PEP-II asymmetric-energy ring at SLAC. The author applies the results of the D° →?−?+?° analysis to extracting CP-violation parameters related to the CKM angle? (or?3) using the decay B− → D{sub?+?−{pi}°} K−.

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-

Search For Cp Violation In Singly Cabibbo Suppressed Four Body D Decays written by and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2011 with categories.
We search for CP violation in a sample of 4.7 x 104 singly Cabibbo suppressed D0 2!K+ K- [pi]+[pi]- decays and 1.8(2.6) x 104 D(s)+ 2!KS0 K+ [pi]+ [pi]- decays. CP violation is searched for in the difference between the T-odd asymmetries, obtained using triple product correlations, measured for D and D decays. The measured CP violation parameters are AT(D0) = (1.0 ± 5.1(stat) ± 4.4(syst)) x 10-3, AT(D+) = ( -11.96 ± 10.04(stat) ± 4.81(syst)) x 10-3 and AT(Ds+) = ( -13.57 ± 7.67(stat) ± 4.82(syst)) x 10-3. This search for CP violation showed that the T-odd correlations are a powerful tool to measure the CP violating observable AT. The relative simplicity of an analysis based on T-odd correlations and the high quality results that can be obtained, allow to consider this tool as fundamental to search for CP violation in four-body decays. Even if the CP violation has not been found, excluding any New Physics effect to the sensitivity of about 0.5%, it is still worth to search for CP violation in D decays. The high statistics that can be obtained at the LHC or by the proposed high luminosity B-factories, make this topic to be considered in high consideration by experiments such as LHCb, SuperB or SuperBelle. The results outlined in this thesis strongly suggest to include a similar analysis into the Physics program of these experiments.

Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of D0 - anti D0 mixing and searches for CP violation in two-body D0 decays, a search for CP violation in the charm decays D" 2!KS0K " and D s" 2!KS0K", KS0[pi]", and a search for direct CP violation in the singly-Cabibbo suppressed D" 2!K+K-[pi]"decays. These studies are based on the fi nal dataset collected by BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these charm decays. The measured mixing parameter yCP = [0.72 " 0.18(stat) " 0.12(syst)]% excludes the no-mixing null hypothesis with a signifi cance of 3.3[sigma].

This thesis describes a high-quality, high-precision method for the data analysis of an interesting elementary particle reaction. The data was collected at the Japanese B-meson factory KEKB with the Belle detector, one of the most successful large-scale experiments worldwide. CP violation is a subtle quantum effect that makes the world look different when simultaneously left and right and matter and antimatter are exchanged. This being a prerequisite for our own world to have developed from the big bang, there are only a few experimental indications of such effects, and their detection requires very intricate techniques. The discovery of CP violation in B meson decays garnered Kobayashi and Maskawa, who had predicted these findings as early as 1973, the 2008 Nobel prize in physics. This thesis describes in great detail what are by far the best measurements of branching ratios and CP violation parameters in two special reactions with two charm mesons in the final state. It presents an in-depth but accessible overview of the theory, phenomenology, experimental setup, data collection, Monte Carlo simulations, (blind) statistical data analysis, and systematic uncertainty studies.
