): Essentially a "fat" version of the electron. It is about 200 times heavier and unstable, decaying into other particles in just two-millionths of a second. The neutral partner produced during muon decays. 3. The Third Generation: The Giants The Tau ( τ−tau raised to the negative power

Despite significant progress in understanding leptons, many questions remain unanswered: lepton
