Original: There are three known types (flavors) of neutrinos: electron neutrino, muon neutrino and tau neutrino, named after their partner leptons in the Standard Model (see table at right).
Simplified: The 3 types of neutrinos are named after the previous three leptons. There is the electron neutrino (ve), the muon neutrino (vÂ), and the tau neutrino (vÏ).
