In the bestiary of particle physics, each of the three charged leptons--the familiar electron and the heavier muon and tau particle - have electrically neutral neutrino counterparts.

Particle physicists chasing ghosts: wispy neutrinos could explain lack of antimatter in universe

The recent OPERA experiment at the INFN's Gran Sasso laboratory in Italy first observed directly a tau particle in a muon neutrino beam generated by pion and kaon decays and sent through the Earth from CERN that is 732 km away [21-23].

Quark annihilation and lepton formation versus pair production and neutrino oscillation: the fourth generation of leptons

Along with the electron and muon, the tau particle and three varieties of neutrinos are now firmly established as members of the lepton group of subatomic particles.
