Available in PDF, EPUB and Kindle. Book excerpt: CP violation and K° charge radius were measured using KL → ?+?-e+e- decays. Specifically, a unique CP-violating decay-plane asymmetry was measured along with the parameters of individual contributions to the decay invariant amplitude: (1) CP-conserving magnetic dipole direct emission form factor, (2) CP-conserving K0 charge radius transition amplitude and (3) an upper limit for the CP-violating electric dipole direct emission amplitude. The measurements were obtained from the data sample accumulated by KTeV experiment at Fermilab. KTeV had two major goals: the measurement of direct CP violation parameter Re(ϵ'/ϵ) and the study of rare kaon decays. The state of the art detector was constructed, commissioned, operated and maintained by an international collaboration of scientists from fourteen institutions. The KL → ?+?-e+esup-/sup data was accumulated over the 1997 and 1999 running periods. During that time hundreds of billions KsubL

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 excerpt: The articles collected in this volume are mainly concerned with the phenomenological description of the 1964 discovery on K° decay that CP invariance was violated in nature. The variety of models developed to explain this CP violation are described together with reprints of more recent definitive experiments, and CP violation in the B° system and the electric dipole moment of the neutron is also covered.
Download or read book CP Violation in the Hadronic Ks Meson Decays written by Michał Silarski and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discrete symmetries as parity P, charge conjugation C and time reversal T, as well as their combinations such as CP and CPT play a fundamental role in particle physics. The CP symmetry violation was discovered unexpectedly in 1964 during the regeneration studies of the neutral K mesons, and result in a far-reaching consequences. In the framework of the Standard Model it implies the existence of the third generation of quarks. Moreover, it is a very important mechanism which could have an essential contribution to the asymmetry between matter and antimatter in the Universe. Parameters describing CP violation in neutral kaon decays were measured with a good precision and at present the main experimental effort is focused on studies of the neutral B and D meson systems. However, there are still several interesting open issues in the kaon physics, like rare Ks meson decays. This work is focused on the measurement of the rare CP violating Ks 3 0 decay branching ratio based on the data sample gathered with the KLOE detector operating at the -factory DA NE in the Italian National Center for Nuclear Physics in Frascati.

Download or read book Polarization and CP Violation Measurements written by Michael Prim and published by Springer Science & Business Media. This book was released on 2014-03-28 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the thorough analysis of the rare B meson decay into φ K* on data taken by the Belle Collaboration at the B-meson-factory KEKB over 10 years. This reaction is very interesting, because it in principle allows the observation of CP-violation effects. In the Standard Model however, no CP violation in this reaction is expected. An observation of CP asymmetries thus immediately implies new physics. This thesis presents an amplitude analysis of this decay and the search for CP violation in detail and discusses methods to solve related problems: The quantification of multivariate dependence and the improvement of numeric evaluation speed of normalization integrals in amplitude analysis. In addition it provides an overview of the theory, experimental setup, (blind) statistical data analysis and estimation of systematic uncertainties.

Available in PDF, EPUB and Kindle. Book excerpt: Interference between K(S) and K(L) decays into the final state pi+pi-gamma has been observed in experiment 731 at Fermilab. By fitting the distribution of decays downstream of a regenerator, a new CP-violation parameter eta+-gamma, analogous to eta+-, has been measured, with its magnitude equal to (2.15 +/- 0.26 +/- 0.20) x 10( -3), and phi+-gamma, the associated phase angle, equal to (72 +/- 23 +/- 17)degrees. Assuming that any difference between this fit value for eta+-, and the previously measured value for eta+- can be attributed to direct CP violation in this decay, a limit of \epsilon'+-gamma\/epsilon

Available in PDF, EPUB and Kindle. Book excerpt: For a long time after the discovery in 1964, by Christenson, Cronin, Fitch and Turlay, that the long-lived neutral kaon decays both into three and into two pions, which has since been taken as proof of CP violation, successive new and more precise experiments confirmed the original evidence and provided results compatible with a phenomenological description confining the CP violation to the mixing between neutral kaons and antikaons. However the Standard Model, with three generations of quarks, linking as it does CP violation to the presence of a single non trivial phase in the Cabibbo-Kobayashi-Maskawa quark mixing matrix, implies that if CP violation exists at all, then it is a general property of weak interactions, appearing in transitions were amplitudes involving all three quark families interfere with each other, producing effects with a magnitude related to that of the CKM coefficients. This fact has stimulated an impressive amount of theoretical work leading in many cases to precise predictions. This publication reviews the field, from both the theoretical and experimental point of view, while planning for the forthcoming experimentation at LHC and considering possible new facilities for kaon, B meson and neutrino physics.
