This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a Dalitz plot analysis of D0 to K0S PI0 PI0 using the CLEO-c data set of 818 inverse picobarns of positron-electron collisions accumulated at center-of-mass energy 3.77 GeV. This corresponds to about 3 million D0-anti-D0 pairs from which we select 1260 tagged candidates with a background of roughly 6%. We find that S-wave features dominate the PI0 PI0 axis of the Dalitz plot, contributing about one-third of the total decay rate, while the K*(892) is the dominant K0S PI0 contribution. Using three tag modes and correcting for quantum correlations we determine that the D0 to K0S PI0 PI0 branching ratio is 1.059% with a statistical uncertainty of 0.049% and a systematic uncertainty of 0.050%.

Naik and published by . This book was released on 2006 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: I present physics concepts, which are useful to understand our analyses, and describe the CLEO III and CLEO-c experiments at the Cornell Electron Storage Ring. I also present motivations for a Dalitz plot analysis of the Cabibbo-suppressed charmed meson decay mode D0 → K+K-pi 0 at CLEO. The analysis uses 9.0 fb-1 of data collected at s ≈ 10.58 GeV with the CLEO III detector. We find the strong phase difference deltaD ≡ argAD 0→K*+K- AD0→K*+K - = 332° +/- 8° +/- 11° and relative amplitude rD ≡ AD0→ K*+K-A D0→K*+K- = 0.52 +/- 0.05 +/- 0.04. This measurement indicates significant destructive interference between D0 → K+(K-pi 0)K*- and D0 → K- (K+pi0) K*+ in the D 0 → K+ K-pi0 Dalitz plot region where these two modes overlap. The fit includes the K*+/- and &phis; resonances and a non-resonant amplitude, and the measured fit fractions for each resonance (with statistical uncertainty only) are (46.1 +/- 3.1)% for the K*+, (12.3 +/- 2.2)% for the K*-, (14.9 +/- 1.6)% for the &phis;, and (36.0 +/- 3.7)% for the non-resonant contribution. We find deltaD = 313° +/- 9° (stat.) and an amplitude ratio of rD = 0.52 +/- 0.05 (stat.) from a second fit which substitutes scalar kappa+/- (mass 878 MeV/c2, width 499 MeV/c2) amplitudes for the non-resonant amplitude. The measured fit fractions for each resonance (with statistical uncertainty only) are (48.1 +/- 4.5)% for the K*+, (12.9 +/- 2.6)% for the K*-, (16.1 +/- 1.9)% for the &phis;, (12.6 +/- 5.8)% for the kappa+, and (11.1 +/- 4.7)% for the kappa-. We also investigate the D 0 → K+K -pi0 Dalitz plot in 281 pb-1 of data collected at s ≈ 3.77 GeV with the CLEO-c detector. We find results which are consistent with the CLEO III analysis. I conclude by summarizing our results and present a brief appendix detailing the K-matrix formalism.

This book was released on 1968 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2 neutral-pion CP-violating decay of the neutral-K2-meson was studied in a recent experiment at the Princeton-Pennsylvania Accelerator. The energy spectrum of generated gamma-rays was obtained for the center-of-mass system of the neutral-K2 and used to measure the branching ratio (neutral-K2 to 2 neutral-pions)/(neutral-K2 to all modes). An upper limit of 0.0031 was obtained by normalizing to the neutral-K2 to 3 neutral-pion decay mode. (Author).
Book Synopsis Time-Dependent CP Violation Measurements by : Markus Röhrken
Download or read book Time-Dependent CP Violation Measurements written by Markus Röhrken and published by Springer Science & Business Media. This book was released on 2013-10-17 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Measurement of the Branching Ratio for Eta-meson Decay Into a Neutral Pion and Two Photons by : Jason William Brudvik
Download or read book Measurement of the Branching Ratio for Eta-meson Decay Into a Neutral Pion and Two Photons written by Jason William Brudvik and published by . This book was released on 2007 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents the results of a measurement of the branching ratio for the rare decay eta → pi0gammagamma. The experiment was carried out in the A2 hall of the Mainz Microtron facility at the Institut fur Kernphysik, on the campus of Johannes Gutenberg Universitat Mainz, in Mainz, Germany. The experiment used the Glasgow-Mainz Tagger, which is a recoil-electron spectrometer, to determine the energy of the incident photons. The principal detector is the Crystal Ball, a highly segmented multiphoton spectrometer covering nearly 4pi steradians surrounding the experimental target. There is also a forward detector, TAPS, which is a multiphoton spectrometer arranged as a downstream wall of detectors. Furthermore, our setup includes an instrument used to differentiate between charged and neutral particles called the Particle Identification Detector, and a liquid hydrogen target. The kinematic-fit technique was used to select the eta → pi 0gammagamma events. The major backgrounds, namely eta → 3pi0 and eta → gammagamma decay and 2pi 0 production were measured simultaneously. The result for the branching ratio is BR(eta → pi0gammagamma) = (2.0+/-0.7) x 10-4. This corresponds to a partial width of Gamma (eta → pi0gammagamma) = 0.26 +/- 0.10 eV. This result is somewhat smaller than the result of recent experiments, it is consistent with theoretical calculations based on Chiral Perturbation Theory.

Book Synopsis Study of the Decay 'neutral-k2 to 2 Neutral-pions'. by : Tuneyoshi Kamae
Download or read book Study of the Decay 'neutral-k2 to 2 Neutral-pions'. written by Tuneyoshi Kamae and published by . This book was released on 1968 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ratio between the two decay rates, Gamma(neutral-K2 to 2 neutral-pions)/Gamma(neutral-K1 to 2 neutral-pions), was studied by comparing the 2 neutral-pions decays in the neutral-K2 beam to those in the regenerated neutral-K1 beam. The advantage of this method is that the result is insensitive to detection efficiency. No free decays neutral-K2 to 2 neutral-pions were observed above the 3 neutral-pion background. On the other hand, 2 neutral-pions decays of neutral-K1 produced in the tungsten regenerator were clearly observed. The comparison of the free decay data with the regeneration data leads to the upper limit of 0.000009 for this ratio. (Author).

Book Synopsis An Introductory Course of Particle Physics by : Palash B. Pal
Download or read book An Introductory Course of Particle Physics written by Palash B. Pal and published by Taylor & Francis. This book was released on 2014-07-29 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: For graduate students unfamiliar with particle physics, An Introductory Course of Particle Physics teaches the basic techniques and fundamental theories related to the subject. It gives students the competence to work out various properties of fundamental particles, such as scattering cross-section and lifetime. The book also gives a lucid summary of the main ideas involved. In giving students a taste of fundamental interactions among elementary particles, the author does not assume any prior knowledge of quantum field theory. He presents a brief introduction that supplies students with the necessary tools without seriously getting into the nitty-gritty of quantum field theory, and then explores advanced topics in detail. The book then discusses group theory, and in this case the author assumes that students are familiar with the basic definitions and properties of a group, and even SU(2) and its representations. With this foundation established, he goes on to discuss representations of continuous groups bigger than SU(2) in detail. The material is presented at a level that M.Sc. and Ph.D. students can understand, with exercises throughout the text at points at which performing the exercises would be most beneficial. Anyone teaching a one-semester course will probably have to choose from the topics covered, because this text also contains advanced material that might not be covered within a semester due to lack of time. Thus it provides the teaching tool with the flexibility to customize the course to suit your needs.
Book Synopsis Measurement of the Strong Phase Delta (kaon Pion) Through the Decay of Quantum-correlated Neutral D-anti-D Meson Pairs by : Eric Justin White
Download or read book Measurement of the Strong Phase Delta (kaon Pion) Through the Decay of Quantum-correlated Neutral D-anti-D Meson Pairs written by Eric Justin White and published by ProQuest. This book was released on 2008 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: We exploit quantum correlations in coherent D 0D0 pairs produced at the psi(3770) resonance to measure the strong phase difference deltaKpi between D0 → K+pi- and D 0 → K-pi+ decays. Using 818 pb-1 of e+e- collisions collected by the CLEO-c detector, we report a measurement of deltaKpi extracted from a Dalitz plot fit of KSpi+pi- in the joint decay D0,D0 → K+/-pi∓, KSpi +pi-. We find a preliminary result of deltaKpi = (32.1 +/- 21.6 +/- 12)°, where the first error is statistical and the second is systematic.
