Related snippets In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions. Two main classes of leptons exist, charged leptons (also known as the electron-like leptons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron. There are six types of leptons, known as flavours, grouped in three generations. The first-generation leptons, also called electronic leptons, comprise the electron ( e− ) and the electron neutrino ( ν e); the second are the muonic leptons, comprising the muon ( μ− ) and the muon neutrino ( ν μ); and the third are the tauonic leptons, comprising the tau ( τ− ) and the tau neutrino ( ν τ) Electrons have the least mass of all the charged leptons.

For every lepton flavor, there is a corresponding type of antiparticle, known as an antilepton, that differs from the lepton only in that some of its properties have equal magnitude but opposite sign. According to certain theories, neutrinos may be their own antiparticle. It is not currently known whether this is the case. Visit also Visit also (backlinks) Flags
