Quasi-Degenerate Neutrinos and Cosmic Baryon Asymmetry

13.7 billion years ago, the universe began from a single point with a big bang creating equal quantities of matter and antimatter. But today antimatter had all but disappeared, leaving matter to form everything that we see around us-from the stars and galaxies, to the Earth and all life that its supports. The answer to imbalance of matter and antimatter in the present universe is found in the simple elusive property of elementary particle the CP violation. This book attempts to answer these problems-the CP Violation (CPV) and baryon asymmetry of the universe. CPV from quark sector is found to be small, and so leptonic CPV is more promising. The book should be helpful to Masters students and research scholars around the globe who are starting to do research on these beautiful challenging topics.
