Tau neutrino

Subatomic particle

The tau neutrino or tauon neutrino is an elementary particle which has the symbol ντ and zero electric charge. Together with the tau , it forms the third generation of leptons, hence the name tau neutrino. Its existence was immediately implied after the tau particle was detected in a series of experiments between 1974 and 1977 by Martin Lewis Perl with his colleagues at the SLAC–LBL group. The discovery of the tau neutrino was announced in July 2000 by the DONUT collaboration. In 2024, the IceCube Neutrino Observatory published findings of seven astrophysical tau neutrino candidates.
