Mounic footprint of simulated extensive air showers

The muon component of extensive air showers produced by the ultra-high energy cosmic rays (E∝10¹⁸ eV) is a subject of numerous studies related to the determination of the primary mass composition or to the properties of the hadronic interactions at the energies beyond the reach of LHC. In our work we investigate the nature of the fluctuations of the muon density at the ground and consider other characteristics of the muon footprint using CORSIKA simulations with no thinning applied to the muon component.
