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]
