CP violation is an intriguing and elusive subject, and current knowledge of it remains limited, on both the experimental and theoretical levels. Researchers lack a fundamental understanding of its origin, and this is all the more important because CP violation is related to the generation problem and mass problem, two of the basic open questions in particle physics. This book provides beginning researchers with a self-contained introduction to the subject, starting at an elementary level and taking the reader to the forefront of current research.
