Neutrinos play a fundamental role in the latest particle physics
theories, such as Grand Unified Theories, theories of supersymmetry, and
superstring theory. Their mass yields an important boundary condition
for grand unification models. They are the best candidates for dark
matter in the universe, and their mass could determine its large scale
structure and evolution. Neutrinos probe the interior of collapsing
stars, and understanding them may lead to a solution of the solar
neutrino problem. In ten chapters written by experts in each of these
fields this book gives a comprehensive presentation of our current
knowledge of the neutrino, of its role in nuclear particle and
astrophysics theories, and of ongoing experimental efforts to learn more
about its own nature. Graduate students and researchers in these fields
will find this book a reliable advanced text and source of reference.
