Book Synopsis Search for CP Violation in D-meson Decays by : Gay Bernadette Stewart
Download or read book Search for CP Violation in D-meson Decays written by Gay Bernadette Stewart and published by . This book was released on 1994 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using data from the Mark III detector at the $esp+esp-$ storage ring at SPEAR, an upper limit of.30 at the 90% confidence level is set on the magnitude of the CP asymmetry $Asb{cp}$ for the CP eigenstate $Dsp0to Ksp+Ksp-.$ This falls within the preexisting limit of.45 @ 90% CL set by FNAL experiment E687 using the same decay. The first measurement of $Asb{cp}$ is made for two other CP eigenstates, $Dsp0to Ksbsp{s}{0}Ksbsp{s}{0}$ and $Dsp0to pisp+pisp-.$ An upper limit for the branching ratio for the decay, $Dsp0to Ksp-pisp+pisp0pisp0pisp0,$ for which evidence was found in the process of measuring $Asb{cp},$ is set at 12.1%.

Download or read book Search for CP Violation in Singly Cabibbo Suppressed Four-body D Decays written by and published by . This book was released on 2011 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Search for CP Violation in $D^0 \to H^+h^-$ Decays at CDF. written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: I report on a measurement of \CP-violating asymmetries ($A_{\Gamma}$) between effective lifetimes of $D^0$ or $\bar{D}^0$ in fully reconstructed $D^0\to K^+ K^-$ and $D^0\to \pi^+\pi^-$ decays collected in $p\bar{p}$ collisions by the Collider Detector at Fermilab experiment. The full CDF data set corresponding to $9.7$ fb$^{-1}$ of integrated luminosity is used. The flavor of the charm meson at production is determined by exploiting the strong-interaction decay $D^{*+} \to D^0 \pi^+$, while the contamination from mesons originated in $b$-hadron decays is evaluated and subtracted from the sample. Signal yields as functions of the observed decay-time distributions are extracted from maximum likelihood fits and used to measure the asymmetries. The results, $A_\Gamma (K^+K^- ) = \bigl( -1.9 \pm 1.5 \mathrm{(stat)} \pm 0.4 \mathrm{(syst)} \bigr)\times10^{-3}$ and $A_\Gamma (\pi^+\pi^- )= \bigl( -0.1 \pm 1.8 \mathrm{(stat)} \pm 0.3 \mathrm{(syst)} \bigr)\times10^{-3}$, and their combination, $A_\Gamma = \bigl( -1.2 \pm 1.2\bigr)\times10^{-3}$, are consistent with the SM predictions and other experimental determinations.

Download or read book Search for CP Violation in the Decays D0 to K- K+and D0 to Pi- Pi written by and published by . This book was released on 2007 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We measure CP-violating asymmetries of neutral charmed mesons in the modes D° → K−K and D° →?−?+ with the highest precision to date by using D° → K−?+ decays to correct detector asymmetries. An analysis of 385.8 fb−1 of data collected with the BaBar detector yields values of a{sup KK}{sub CP} = (0.00 ± 0.34 (stat.) ± 0.13 (syst.))% and a{sup?{pi}}{sub CP} = ( -0.24 ± 0.52 (stat.) ± 0.22 (syst.))%, which agree with Standard Model predictions.
Download or read book CP Violation in B and D Decays written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-leptonic B decays offer the best opportunity to discover the violation of CP invariance outside the neutral K system. Employing the Standard Model one predicts - with reasonable confidence - CP asymmetries of up to 205 (or even more in some cases). The branching ratios for the individual exclusive modes of interest are not expected to exceed the 10−3 level in most cases; the identification of such decays poses non-trivial problems. It is shown that by summing intelligently over appropriate classes of decays one can greatly enhance statistics without jeopardizing the signal. Data that contain 106 produced B mesons would allow meaningful searches for CP violation. It is noted that ''New Physics'' could lead to CP asymmetries in D° decays of order 1%. Due to higher branching ratios one can search for such effects in samples of 106 produced D mesons. 7 refs.
Book Synopsis Search for CP Violation in B0 to D(*)±K0 Π± Decays by : Troels C. Petersen
Download or read book Search for CP Violation in B0 to D(*)±K0 Π± Decays written by Troels C. Petersen and published by . This book was released on 2004 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the idea of considering three-body decays with final state B to DKpi in the pursuit of the notoriously elusive unitary angle gamma, the initial steps towards its measurement are presented. Using a sample of approximately 88 million BBbar pairs collected with the BaBar detector at the PEP-II collider, a measurement of the branching fractions BO to D+- KO pi-+ and BO to D*+- KO pi-+ are presented for the entire Dalitz region: Br(BO to D+- KO pi-+) = (4.97 +- 0.69 +- 0.55) x 10^(-4) Br(BO to D*+- KO pi-+) = (3.00 +- 0.66 +- 0.29) x 10^(-4). In both decay modes the dominant resonance is the K*+-(892) between the neutral kaon and the charged pion. Measuring the branching fractions of the corresponding resonant two-body decays yields: Br(BO to D+- K*-+) = (4.78 +- 0.58 +- 0.53) x 10^(-4) Br(BO to D*+- K*-+) = (3.22 +- 0.59 +- 0.29) x 10^(-4). Performing a time-dependent CP asymmetries fit of the resonant decay mode BO to D+- K*-+ yields: C = 0.93 +- 0.18 +- 0.03 ABS[lambda] = 0.19 +- 0.25 +- 0.04 S = 0.18 +- 0.28 +- 0.02 Delta S = 0.08 +- 0.28 +- 0.02. As the amplitude ratio ABS[lambda] is consistant with zero, no interference sensitive to gamma can be established at this point.

This book was released on 2011 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: We search for CP violation in a sample of 20,000 Cabibbo-suppressed decays, D+ → K+K{sub S}°?+?−, and 30,000 Cabibbo-favored decays, D{sub s}+ → K+K{sub S}°?+?−. We use 520 fb−1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e− collider operating at center of mass energies near 10.6 GeV. We search for CP violation in the difference between the T-odd asymmetries obtained using triple product correlations of the D+ (D{sub s}+) and D− (D{sub s}−) decays, respectively. The T violation parameter values obtained are ?{sub T} (D+) = (-12.0 ± 10.0{sub stat} ± 4.6{sub syst}) x 10−3 and ?{sub T}(D{sub s}+) = (-13.6 ± 7.7{sub stat} ± 3.4{sub syst}) x 10−3, which are consistent with the Standard Model expectations.
