Why Are Muons Unstable?

The muon is unstable because it decays into an electron and two neutrinos in about 2μs. But a muon is not in some sense an excited electron. Both particles are excitations in a quantum field and they are both as fundamental as each other.

Are muons unstable?

It is classified as a lepton. As with other leptons, the muon is not known to have any sub-structure – that is, it is not thought to be composed of any simpler particles. The muon is an unstable subatomic particle with a mean lifetime of 2.2 μs, much longer than many other subatomic particles.

Is muon subject to strong interaction?

The muon is considered nowadays a fundamental particle of matter, like the electron, its neutrino and the quarks constituents of the nuclear matter. Like the electron, it is not subject to strong interactions. It has also an alter ego without electric charge, the muonic neutrino or neutrino-mu.
