Book Description
The authors present a preliminary measurement of the time-dependent CP asymmetries in decays of B° mesons to the final states D{sup (*)}[pi] using data collected by the BABAR experiment at the PEP-II storage rings. B mesons decaying to D[pi] are fully reconstructed, while events containing B → D*[pi] are selected using a full or a partial reconstruction technique. These results can be interpreted in terms of a constraint on the angles of the unitarity triangle to set a lower bound on

Book Description
Presenting the proceedings of FPCP 2018, this book reviews the status quo of flavor physics and discusses the latest findings in this exciting area. Flavor physics has been instrumental in the formulation and understanding of the standard model, and it is possible that the direction of new physics will be significantly influenced by flavor sector, also known as the intensity frontier, making it possible to indirectly test the existence of new physics up to a very high scale, beyond that of the energy frontier scale accessible at the LHC. The book is intended for academics around the globe involved in particle physics research, professionals associated with the related technologies and those who are interested in learning about the future of physics and its prospects and directions.

Book Description
A study of the potential of the BABAR detector at PEP II to measure CP violation using the vector-vector channel B{sup 0} {yields} D*{sup +}D*{sup -} is presented. The decay mode, although not a CP eigenstate, is sensitive to the angle {beta} of the unitarity triangle, a fundamental measure of CP violation in the neutral B system. The decay mode B{sup 0} {yields} D*{sup +}D*{sup -} is reconstructed in a variety of channels and a study of the separation of the CP eigenstate contributions and extraction of the angle {beta} is presented. The contribution of this channel is compared with other similar channels, and the overall prospects for measuring the angle {beta} in the first years of BABAR running is summarized.

Book Description
The BABAR experiment at the PEP-II B factory at SLAC has collected over 37 10[sup 6] BB pairs in the years 2000 and 2001. Based on this data sample, various studies of CP violation in the B system are presented, including the first observation of CP violation outside the kaon system and a measurement of the CKM parameter sin(2[beta])= 0.59[+-] 0.14(stat)[+-] 0.05(syst). Studies on direct CP violation and CP violation in mixing are also presented.

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.
