Tauoni
Tauoni, also known in English as tauons, are elementary particles in the Standard Model. They are the heaviest charged leptons, forming the third generation of leptons alongside the electron and muon. They carry electric charge −1 and have spin 1/2. Like other leptons, tauoni do not carry color charge and interact via the weak and electromagnetic forces, as well as gravity, but not via the strong interaction.
The tauoni have a rest mass of about 1776.86 MeV/c^2 and a very short mean lifetime of
Representative decay modes include tau → e νe ντ, tau → μ νμ ντ, and hadronic channels such as tau → π− ντ, tau →
The tauoni were discovered in 1975 by Martin Perl and colleagues at the SLAC Stanford Linear Accelerator
Nomenclature varies by language; the term tauon is traditional, with tauoni used as a plural in some
