Leptons: A category name for electrons, and particles like electrons. Heavier cousins of the electron are the muon (found in cosmic rays) and the tau. As far as we can tell, they don't have pieces making them up. Neutrinos: Very light, neutral particles produced in some kinds of nuclear interactions. A neutron will decay into a proton and an electron and an electron antineutrino. There are three flavors, one corresponding to each lepton (electron neutrino, muon neutrino, and tau neutrino).
