- a lepton similar in most respects to the electron except that it is unstable, it may be positively charged, and its mass is approximately 207 times greater; the positively charged muon is the antiparticle of the negatively charged muon. Symbol: μ

Historical Examples of muon
That is, if the muon did not exist, what effect would this have on the structure of matter?
The behavior of the muon is well understood, but its role as one of the elementary particles is unknown.
The muon is unstable, eventually undergoing a radioactive decay into an electron.
Although the muon does not experience nuclear forces, it can interact weakly with nuclei.
- a positive or negative elementary particle with a mass 207 times that of an electron and spin 1/2 . It was originally called the mu meson but is now classified as a lepton
Word Origin for muon
- An elementary particle in the lepton family having a mass 209 times that of the electron, a negative electric charge, and a mean lifetime of 2.2 X 10-6 seconds. The muon was originally called the mu-meson and was once thought to be a meson. See Table at subatomic particle.
