Keywords:CP Violation;Quark Mixing Matrix;Charm Decays;B Decays;Nonleptic Interactions;Heavy QuarksReview: “Similar material is most often available in journals, but the book accomplishes a valuable service in drawing it together … the one that will probably have the greatest utility and longest lifespan is the survey of B meson physics by I Bigi, V Khoze, N Uraltsev and A Sanda … Bigi et al. here provide the most thorough and readable account of the issues that I know of. I have seen no review comparable to the excellent summary of electric dipole moments by S Barr and W Marciano … the volume offers a generally readable entry into this field for a reader who has a basic background in particle physics.” John F Donoghue Science “… this book performs a very useful service for anyone active or interested in CP violation, both as a source of primary information and as a work of reference.” K J Peach J Phys.

Book Description
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.

Book Description
CP violation is one of the most subtle effects in the Standard Model of particle physics and may be the first clue to the physics that lies beyond. Charge conjugation, C, and parity, P, are symmetries of particle interactions. C corresponds to the operation of replacing a particle by its antiparticle, while P is the operation of mirror reflection. Before 1956, it was believed that these were also symmetries of the interactions of elementary particles. In 1956, C S Wu found evidence for P violation in the weak interaction. Theorists proposed that the combination of CP would be a symmetry of the weak interaction. In 1964, Christenson, Cronin, Fitch and Turlay found the first evidence for the violation of CP symmetry in the decays of kaons.Although Kobayashi and Maskawa then showed how the Standard Model can accommodate the observed CP violation, Wolfenstein pointed out that it is also possible that there is a new interaction in addition to the usual four, called the superweak interaction, which is responsible for the asymmetry. To test this idea, the observation of a different type of asymmetry, called direct CP violation, is required; in the kaon sector, very precise measurements of the ratio of kaon decay rates are necessary. In B decay modes where a second order weak process whimisically named “penguin” interferes with another suppressed, first order “tree” amplitude, it may also be possible to observe these direct CP-violating effects.B physics and CP violation is now one of the major growth areas in high energy physics. Nearly every major high energy physics laboratory now has a project underway to observe the large CP asymmetries expected in the B sector and to test the consistency of the Standard Model. The unitarity of the Kobayashi-Maskawa mixing matrix in the Standard Model implies the existence of three phases, called alpha, beta and gamma, which can be determined by the measurements of CP asymmetries in B decays. About 200 participants gathered in Hawaii in March 1997 to discuss the progress in the field, and this important book constitutes the proceedings of that conference.

Book Description
Why did the matter in our Universe not annihilate itself with antimatter immediately after its creation? The discovery of CP violation may answer this fundamental question. From the basics to the front line of research, this timely account presents background information and theoretical tools necessary for understanding this phenomenon. Early chapters explore charge conjugation, parity, and time reversal symmetries before introducing the Kobayashi-Maskawa ansatz for CP violation and examining the theoretical understanding of CP violating K meson decays. Following chapters reveal how the discovery of B mesons provides a new laboratory in which to study CP violation and predict CP violation in B meson decays and rare K meson decays. Later chapters continue the search for a new fundamental theory and address the problem of baryogenesis in the big bang universe. The importance of close links with experiment is stressed throughout. Each chapter concludes with problems. Detailed references are included. This book is suitable for graduate students and researchers in particle physics, atomic and nuclear physics and the history and philosophy of science.

Book Description
The author explores the possibility of using CP violation in B decays to detect the presence of physics beyond the Standard Model. He first studies the possibility of new physics in the B-{anti B} mixing amplitude. He discusses a construction to extract information about the phase and magnitude of the new physics contribution, as well as the CKM parameters in a model independent way. He points out the difficulty of carrying through this program induced by hadronic uncertainties and discrete ambiguities, and suggests additional measurements to overcome these problems. He then studies the possibility of new physics contributions to the B meson decay amplitudes. The author emphasizes the sensitivity of the B → [phi]K{sub S} decay to these new contributions, and explains how this sensitivity can be quantified using experimental data on SU(3) related decays. Finally, he analyzes a number of models where the B decay amplitudes are modified.

Book Description
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.

Book Description
The phenomenology of the violation of the CP symmetry by the fundamental interactions is a fascinating subject which, even after decades of dedicated theoretical and experimental research, is far to be fully understood. While investigations of the K and B systems have and will continue to play a central role in this field of research, in depth examinations of the D mesons sector have yet to be performed with enough precision, leaving a gap in our knowledge. This book describes a search for CP violation in Cabibbo-suppressed neutral D decays to two charged pions or kaons performed using the proton-antiproton collisions recorded at the Fermilab's TeVatron collider by the CDF experiment during February 2002 and January 2010. The result is the current most accurate determination of CP-violating asymmetries in these decays and represents a pioneering measurement of high precision CP violation in the charm sector at hadron colliders that has been of inspiration for the similar studies which are now ongoing at the CERN's Large Hadron Collider.
