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.Contents: From Massless to Massive Neutrinos:IntroductionThe Standard Model and the NeutrinoMassive NeutrinosDirac versus Majorana MassesNeutrino OscillationsSolar NeutrinosModels of Neutrino Mass:Neutrino Mass SU(2)L x U(1)Y ModelsNeutrino Mass in Left-Right Symmetric ModelsNeutrino Mass in Grand Unified ModelsNeutrino Mass in Supersymmetric ModelsLarge Neutrino MixingsImplications of Neutrino Mass:Kinematic Tests of Neutrino MassElectromagnetic Properties of NeutrinosDouble Beta DecayRelated ProcessesNeutrino Properties in Material MediaNeutrinos from SupernovaeNeutrino CosmologySterile NeutrinosReadership: Graduate students and researchers in high energy physics and astrophysics.Key Features:Unique representation of current state-of-art in unconventional and nature-inspired computing; comprehensive and self-consistent overviews of advanced prototypes of biologically inspired computing devices and robotsHighly illustrated guide to modern unconventional computing; results of unique experiments with propagating decentralised amoeba-like computing devices and manipulatorsStrong appeal of the subject to general audience; all theoretical topics are self-consistent and require minimal knowledge in computer scienceDo-It-Yourself appeal: all experiments presented in the book can be implemented at home or office without access to any specialised laboratory equipment; simplicity of comprehensive experiments will make the book an ideal textbook in courses in natural and nature-inspired computing, and biological roboticsFirst-class handbook for bio-inspired computing, robotics, computer science and engineering laboratory studies, and self-learning
