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.

The second edition is updated and corrected and contains new chapters on recent developments. From reviews of the first edition: "This book captures the exciting developments of grand unification and supersymmetry of fundamental interactions in quantum field theory... gives a self-contained field-theoretic treatment of the complete subject... almost every possible development is included here." #Mathematical Reviews#1

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.

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.

A journey into one of the greatest mysteries of modern science, this book explores the hidden world of dark matter—and the proposition that it may reside in a parallel "mirror" universe existing alongside our own.Astronomical observations have established that most of the matter in the universe is in an invisible form, known as dark matter. Serendipitously discovered by Fritz Zwicky in 1930, the existence of dark matter was confirmed by detailed observations of the speed of stars in galaxies by Kent Ford and Vera Rubin in the 1970s. In 2001, the explorer mission launched by NASA provided further confirmation and established that dark matter constitutes more than 80% of matter in the universe. It has since become clear that dark matter explains how galaxies formed from the uniformly expanding cosmic fluid as the universe evolved, thereby solving another major mystery of the cosmos.The question at the frontier of current research in cosmology and particle physics is this: what exactly is dark matter? Many high-sensitivity experiments have been carried out to answer this question, but so far they have been unsuccessful. This has led to speculation that dark matter may exist in an alternate universe, where particles experience different forces than we do and interact with familiar matter only through gravity. This would explain why laboratory detectors—built from the material of the visible world—have failed to find such matter. We call this alternate realm the "mirror universe" or "replicate universe". This universe supposedly coexists side by side with our own and contains identical copies of our universe's matter and forces. This daring idea was first proposed in 1956 by T D Lee and C N Yang and has since been elaborated and applied to dark matter physics. Focusing on lucid explanations instead of dense equations, this book introduces the fascinating concept of the "replicate universe" to a general audience and reveals its powerful implications for our understanding of the universe.

Are neutrinos massless particles as predicted by the standard model of electroweak interactions? There are however many reasons to suspect that neutrinos may indeed be massive and understanding the neutrino mass may hold the key to our understanding of physics beyond the standard model.This book provides a comprehensive overview of our present understanding of neutrino mass in unified gauge theories, its phenomenological and cosmological implications. It is divided into four parts. The first part presents a model independent discussion of the properties of the neutrino and nature of the neutrino masses. Part 2 deals with neutrino masses in unified and grand unified theories. In Part 3, phenomenological implications of neutrino mass is discussed. This includes neutrino oscillations, neutrinoless double beta decay and electromagnetic properties of neutrinos. Part 4 considers the solar neutrino puzzle, SN1987A and cosmological constraints on the neutrino properties. The book is meant for beginning and advanced graduate students in particle physics as well as active researchers in the field. It contains an extensive list of references to the original literature.

Offers an up-to-date discussion on the theory, phenomenology, cosmology and astrophysics of massive neutrons. It includes a chapter on mathematical preliminaries that lead to the derivation of the standard model and properties, and which gives a discussion on the nature Dirac and Majorana masses for neutrinos and the various extensions of the standard model that explain the small neutrino mass. Various phenomena related to neutrino mass such as rare decays of muons and kaons, double beta decay, and neutrinos in a medium, are discussed. The final chapters include discussions on solar and supernova neutrinos and neutrino cosmology. References to the existing literature are included.

This book is a collection of theoretical advanced summer institute lectures by world experts in the field of collider physics and neutrinos, the two frontier areas of particle physics today. It is aimed at graduate students and beginning researchers, and as such, provides many pedagogical details not generally available in standard conference proceedings.
