In the standard model (SM) of particle physics neutrinos are massless and chargeless spin ½ particles. But the discovery of neutrino oscillations has shown that neutrinos have mass. From neutrino oscillations, we know only differences of mass-squared but not the absolute masses of individual neutrinos. In this article, we discuss neutrino oscillation and neutrino mass briefly.
