In particle physics, a lepton is an elementary particle of half-integer spin (spin ⁠1/2⁠) that does not undergo strong interactions. [ 1 ] Two main classes of leptons exist: charged leptons (also known as the electron -like leptons or muons), including the electron, muon, and tauon, and neutral leptons, better known as neutrinos.

Leptons are a group of subatomic particles that do not undergo strong interactions. They are one of the basic building blocks of matter. There are six types of leptons, known as flavors: electron, muon, tau, electron neutrino, muon neutrino, and tau neutrino.

The six basic leptons: electrons, muons, tauons, electron neutrinos, mu neutrinos, and tau neutrinos, respectively Leptons are elementary particles with spin 1/2 (a fermion) that are not affected by strong nuclear force. They are a family of particles that are different from the other known family of fermions, the quarks.

We have experimental evidence for six different kinds of leptons – three negatively electrically charged leptons, and three electrically neutral. The best known electrically charged leptons are: the electron (e) the muon (μ) the tauon (τ) The three electrically neutral leptons are the neutrinos (ν).
