Meaning
Leptons are a type of fermion which are unaffected by the strong nuclear interaction.
About Leptons
- Leptons are fundamental particles as they are not made of any smaller particles.
- Leptons include:
- Electron - A type of lepton with a mass of 9.11x10-31kg and a charge of -1.60x10-19 Coulombs.
- Muon - A type of lepton often referred to as a 'heavy electron' same charge as an electron (-1.60x10-19) Coulombs but a mass 206 times the mass of an electron.
- Neutrino - A type of lepton with zero charge and negligible mass.
- Leptons are affected by the:
