Book Description
A review is presented of the experimental efforts at the Brookhaven AGS to study the nature of CP violation in the decays of kaons. The current research focuses on sensitive searches for a violation of time-reversal (T) invariance in the decay K ..-->.. ..mu nu../sub ..mu../ as evidenced by a nonzero component of muon polarization normal to the decay plane. The ongoing program of research includes a study of direct CP violation in the decays of neutral kaons through a precise (1%) measurement of absolute value of eta00/absolute value of eta/sub +-/, the ratio of the CP violating amplitudes for the decays of neutral kaons into neutral and charged two pion final states. Results will be presented on the decay K/sub L/° ..-->.. ..pi..−..mu ... nu../sub ..mu../, where we have found the ratio of T violating to T conserving transverse polarization of the muons to be = 0.004 +- 0.009, consistent with T invariance. Preliminary results for the polarization of muons in the decay K ..-->.. ..pi..°..mu../sup +/..nu../sub ..mu../ will be discussed.

Book Description
CP violation is essential to understanding the universe in which we live. Without it there can be no dominance of matter over anti-matter. New experimental facilities, such as the B-factories, and new experimental techniques promise the first real advances in our understanding of this phenomenon since its discovery in the mid-60's.The Workshop on CP violation brought together representatives of all the major experimental collaborations and key theorists. The result is an excellent introduction to the directions in which the field will move in the next few years.

Book Description
TASI is the premier U.S. summer school in theoretical elementary particle physics. This volume is a collection of lectures given at TASI 1994. These lectures provide an overview of many basic topics in the field, as well as specific discussions of the theme of this year's course, which involved the frontiers of the present Standard Model. The volume should be extremely useful to students and young researchers as it provides pedagogical presentations of important topics.

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
This thesis reports on the final measurement of the flavor-mixing phase in decays of strange-bottom mesons (B_s) into J/psi and phi mesons performed in high-energy proton-antiproton collisions recorded by the Collider Experiment at Fermilab. Interference occurs between direct decays and decays following virtual particle-antiparticle transitions (B_s-antiB_s). The phase difference between transition amplitudes (“mixing phase”) is observable and extremely sensitive to contributions from non-standard-model particles or interactions that may be very hard to detect otherwise – a fact that makes the precise measurement of the B_s mixing phase one of the most important goals of particle physics. The results presented include a precise determination of the mixing phase and a suite of other important supplementary results. All measurements are among the most precise available from a single experiment and provide significantly improved constraints on the phenomenology of new particles and interactions.
