Muons are fundamental subatomic particles classified as leptons, possessing properties highly analogous to the electron but with significantly greater mass. They are predominantly observed naturally through the interactions of cosmic rays in the Earth's upper atmosphere, where higher-energy particles create secondary showers that yield these particles. Due to their intrinsic mass, muons possess a relatively short mean lifetime compared to the electron, leading them to decay over time. Their existence and study provide vital information regarding particle physics, atmospheric composition, and the mechanics of high-energy interactions across cosmic distances.
