Neutrino mass in particle physics and astrophysics

Abstract

This paper discusses the search for neutrino oscillations as a probe for the possibility of small neutrino masses. None of the experiments provides definitive evidence for neutrino mass, but there is a strong indication of a mass from the study of neutrinos from the Sun. If non-zero neutrino masses are definitely confirmed, it would have important implications for particle physics, astrophysics and cosmology.
