Lepton
Any of a class of elementary particles that are not affected by the strong nuclear force. The leptons comprise the electron, muon, and tau, and their neutrinos (the electron neutrino, muon neutrino, and tau neutrino), as well as their six antiparticles.
In July 2000, researchers at Fermilab, in the USA, amassed the first direct evidence for the existence of last neutrino remaining to be discovered, the tau lepton.
