| Abstract: | In the standard
model (SM) of particle physics, neutrinos are massless and neutral spin ½
particles. But from recent experiments, it is found that neutrinos undergo
flavour oscillations, violating lepton flavour conservation which implies that
neutrinos have non-zero mass. The absolute scale of neutrino masses is very
important for understanding the evolution and the structure formation of the
Universe as well as for nuclear and particle physics beyond the present
standard model. In this review article, first we have tried to put some logical
arguments to support that neutrinos have mass. Then various ways of determining
the neutrino masses are briefly discussed and their sensitivities are compared.
Neutrino mass is a window for new physics beyond the SM. |
