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

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.

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.
