Muon Puzzle in Cosmic Rays and Its Possible Solution

Abstract

There was a lot of puzzles in the history of the discovery and investigations of the muon itself and the muon component of cosmic rays. The last of them is an excess of high-multiplicity muon groups that grows with increasing energy of primary cosmic rays and which is detected in various experiments. An excess of muons that have ultrahigh energies (above 100 TeV) is the second aspect of the muon puzzle. Various approaches to solving the muon puzzle that are associated with measuring the energy features of the muon component of cosmic rays are considered.
