The idea of a neutrino was derived from experiments demonstrating continuous beta decay spectra and, at the same time, it resolved problems that had arisen in the determination of nuclear constituents. The unusual features of the neutron, especially its disintegration, led to the introduction and subsequent detection of a new particle, the neutrino. In this book, the authors present current research in the study of the discovery, detection and new developments in neutrinos. Topics include the way to a deterministic tachyon model of neutrino; neutrino emissivity and light species; and the magnetic moment and electric dipole moment of Tau-neutrinos.
