Neutrinos as elementary particles known as leptons. Currently there is 3 known neutrinos; electron,
Muon and Tau neutrino. They also have 3 corresponding anti-neutrinos. Neutrinos react via the
weak and gravitational force. Their mass is as of yet unknown, but there are very good estimates
on the relative differences in mass between the 3 types of neutrinos. Some of the more famous
neutrino experiments include SNO (Canada), Super-Kamiokande (Japan), MiniBooNE (USA),
etc.
