has definition The generic name for any spin-1/2 particle which does not feel the strong nuclear force. The six known leptons are the electron, the muon, the tau lepton, and their respective neutrinos. The name was originally coined to refer to light particles. | ![has source: Coughlan, G.D., Dodd, J.E. 1999 The Ideas of Particle Physics, Cambridge University Press, 2001-09-27 09:28:03.0 has source: Coughlan, G.D., Dodd, J.E. 1999 The Ideas of Particle Physics, Cambridge University Press, 2001-09-27 09:28:03.0](facet.gif) |
has definition Any fermion that does not participate in the strong interactions. Leptons include the electron family and the muon family. | ![has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:28:03.0 has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:28:03.0](facet.gif) |

has definition Elementary particle like the electron and neutrino that do not experience the strong nuclear force. Unlike the strongly interacting hadrons, the leptons have small masses. | ![has source: Peat, D. 1988 Superstrings and the Search for a Theory of Everything, Contemporary Books, 2001-09-27 09:28:03.0 has source: Peat, D. 1988 Superstrings and the Search for a Theory of Everything, Contemporary Books, 2001-09-27 09:28:03.0](facet.gif) |
