A lepton is a spin 1/2 elementary particle that is not subject to the strong nuclear force, such as an electron, muon or neutrino.[1] Leptons can be charged as in the case of the electron (e), muon (μ) and tau (τ) (all negatively charged), and the corresponding antileptons (all positively charged), or can be neutral like the electron neutrino (νe) or tau neutrino (ντ). Having spin 1/2, all leptons are fermions.[2]
