The Tauon

Symbol: τ-
Group: fermion, lepton
Rest mass: 1.91 u
Charge: -1 e
Mean lifetime: 2.9 x 10-13 sec
Spin: 1/2
Generation: 3
The tauon is a particle very similar to the muon, but much heavier and more unstable than this. It decays to this or to electrons and to the according anti- neutrinos or even to hadrons.
