Image:Muon Decay

Description: Computer artwork showing muon decay. Muons are unstable elementary particles and are heavier than electrons and neutrinos but lighter than all other matter particles. They dominant muon decay mode (sometimes called the Michel decay after Louis Michel) is the simplest possible: the muon decays to an electron, an electron-antineutrino, and a muon-neutrino. Muons are produced in large quantities when cosmic rays bombard the Earth's atmosphere. These collisions result in the production of a shower of pions and kaons which quickly decay into muons.
