单词	neutrino
释义	neutrino A lepton (see also elementary particles) that exists in three forms, one in association with the electron, one with the muon, and one with the tau particle. Each form has its own antiparticle. The neutrino, which was postulated in 1931 to account for the ‘missing’ energy in beta decay, was identified tentatively in 1953 and, more definitely, in 1956. Neutrinos have no charge, are thought to have zero rest mass, and travel at the speed of light. In some grand unified theories they are predicted to have nonzero mass, but there is no conclusive evidence for this
