A muon is an elementary particle in the Standard Model of particle physics. It carries a negative elementary charge −e, where
- e = 1.60218 × 10-19 C.
The muon mass is 1.88353 × 10-28 kg = 105.7 MeV/c2, which is 206.8 times the mass of the electron.
Muons are not stable particles, and decay with a mean lifetime of 2.2 × 10-6 s.
