Neutrino
The three types of neutrinos are named after the three leptons that have electric charge. There is the electron neutrino (ve), the muon neutrino (vµ), and the tau neutrino (vτ). Each neutrino has an antiparticle, called an antineutrino. Therefore, there is an electron antineutrino, a muon antineutrino, and tau antineutrino.
