Book Description
The methods to measure the angle[gamma] of the CKM unitarity triangle at the B factories are presented. Special emphasis is given to the measurement of sin(2[beta] + [gamma]) using the B° → D*{sup {+-}} [pi]{sup {-+}} decays which has already produced results providing an interesting constraint in the [rho] - [eta] plane. Various methods using B → DK decays are also presented.

Book Description
This book presents the latest results on the branching fraction and phase space distribution of B0 and Bs0 decays into final states including excited neutral charm mesons. This work represents four years of research, and the book describes in detail all the necessary steps and techniques required to perform a physics analysis of the data recorded by the LHCb experiment in the years 2016–2018. Although the results presented in this book represent the first measurement of such decays, the text is written in a manner accessible to Ph.D. students and early career researchers. Thus, all the contents included in this book are described in a pedagogical way, including technical details that would allow the results to be reproduced in future. In addition to the methodology used to perform these measurements, the book also includes a description of the theoretical background required to interpret the results presented, as well as a technical description of the LHCb detector, which provided the data sample used in this study.

Book Description
The prospects for measuring the angle with present day B factories are examined. A number of approaches are discussed with reference to recent preliminary measurements based on a data sample of approximately 88 million B{bar B} pairs collected by the BaBar detector at the PEP-II asymmetric B Factory at SLAC.

Book Description
We report on our recent measurements of the Cabibbo-Kobayashi-Maskawa CP-violating phase [gamma] and of related CP-asymmetries and branching fraction ratios. The measurements have been performed on samples of up to 465 million B{bar B} pairs collected by the BABAR detector at the SLAC PEP-II asymmetric-energy B factory in the years 1999-2007.

Book Description
Measuring the angle [gamma] is an important part of over-constraining the Unitarity Triangle to test Standard Model predictions. There are a number of methods to measure [gamma], and we present results on the progress made in measuring [gamma] with B meson decays, using data collected with the BABAR detector at the PEP-II asymmetric energy ee− collider at SLAC.

Book Description
Measuring the angle [gamma] of the unitarity triangle is an important part of overconstraining the Standard Model's explanation of CP violation and testing for new physics contributions to CP violation. Although there are many ways to measure [gamma], all of them have significant experimental or theoretical challenges. This talk presents progress at the babar experiment toward measuring [gamma] using B meson decays.
