Cosmic rays are high-energy particles from outer space that strike Earth's atmosphere, generating showers of secondary particles, such as muons, that can reach the planet's surface. In recent years, ground-based experiments have detected more cosmic muons than current theoretical models predict, a discrepancy known as the muon puzzle.
