SUPERSYMMETRY, SUPERGRAVITY, AND UNIFICATION This unique book gives a modern account of particle physics and gravity based on supersymmetry and supergravity, two of the most significant developments in theoretical physics since general relativity. It begins with a brief overview of the history of unification and then goes into a detailed exposition of both fundamental and phenomenological topics. The topics in fundamental physics include Einstein gravity, Yang–Mills theory, anomalies, the standard model, supersymmetry,andsupergravityandtheconstructionofsupergravitycouplings with matter and gauge fields as well as computational techniques for SO(10) couplings. The topics of phenomenological interest include implications of supergravity models at colliders, CP violation, and proton stability, as well as topics in cosmology such as inflation, leptogenesis, baryogenesis, and dark matter. The book is intended for graduate students and researchers seeking to master the techniques for building unified models. pran nathisMatthewsUniversityDistinguishedProfessorofPhysicsatNorth- easternUniversityinBoston.Hehasmadepioneeringcontributionstothedevel- opment of supergravity theory and its applications to particle physics including the mSUGRA model. He has also contributed to the development of effective Lagrangian methods, pion physics, current algebra, solving the U(1) problem, dark matter and proton stability in unified models. He is the founding chair of the Supersymmetry and Unification of Fundamental Interactions (SUSY) con- ference and the Particles, Strings and Cosmology (PASCOS) symposium. He is a Fellow of both the American Physical Society and of the American Associa- tion for the Advancement of Science, and a recipient of the Humboldt Prize in physics.
