The recent groundbreaking discovery of nonzero neutrino masses and oscillations has put the spotlight on massive neutrinos as one of the key windows on physics beyond the standard model as well as into the early universe. This third edition of the invaluable book Massive Neutrinos in Physics and Astrophysics is an introduction to the various issues related to the theory and phenomenology of massive neutrinos for the nonexpert, providing at the same time a complete and up-to-date discussion on the latest results in the field for the active researcher. It is designed not merely to be a guide but also as a self-contained tool for research with all the necessary techniques and logics included. Specially emphasized are the various implications of neutrino discoveries for the nature of new forces. Elementary discussions on topics such as grand unification, left-right symmetry and supersymmetry are presented. The most recent cosmological and astrophysical implications of massive neutrinos are also dealt with.

Derived from a course given at the University of Maryland for advanced graduate students, this book deals with some of the latest developments in our attempts to construct a unified theory of the fundamental interactions of nature. Among the topics covered are spontaneous symmetry breaking, grand unified theories, supersymmetry, and supergravity. the book starts with a quick review of elementary particle theory and continues with a discussion of composite quarks, leptons, Higgs bosons, and CP violation; it concludes with consideration of supersymmetric unification schemes, in which bosons and leptons are considered in some sense equivalent. The third edition will be completely revised and brought up to date, particularly by including discussions of the many experimental developments in recent years.

Every second of every day, we are exposed to billions of neutrinos emitted by the Sun, and yet they seem to pass straight through us with no apparent effect at all. Tiny and weakly interacting this subatomic particle may be, but this book will show you just how crucial a role it has played in the evolution of the elements in the universe, and eventually, ourselves.We first start with an introduction to the basics of subatomic physics, including brief backgrounds on the discoveries that set the stage for major 20th century advances. The author, a distinguished theoretical physicist who has researched neutrinos for over thirty years, next explains in nontechnical language how and why the neutrino fits into the wider story of elementary particles. Finally, the reader will learn about the latest discoveries in the past half century of neutrino studies. This semi-popular science book will appeal to any physics students or non-specialist physicists who wish to know more about the neutrino and its role in the evolution of our universe.
