 <content>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.</content>
