Book Description
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.

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
This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.

Book Description
Direct CP violation can exist in untagged, neutral B-meson decays to certain self-conjugate, hadronic final states. As a necessary condition, the resonances which appear therein must permit the identification of distinct, CP-conjugate states--in analogy to stereochemistry, we term such states ''CP-enantiomers.'' These states permit the construction of CP-even and CP-odd amplitude combinations and of observables sensitive to their interference, which are non-zero if direct CP violation is present. The decay B[yields][pi][sup+][pi][sup -][pi][sup 0], containing the distinct CP-conjugate states[rho][sup+][pi][sup -] and[rho][sup -][pi][sup+], provides one such example of a CP-enantiomeric pair. We illustrate the possibilities in various multi-particle final states.

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.
