Description

Some discrepancies have been reported between observed and simulated muon content of extensive air showers: the number of observed muons exceeded the expectations in HiRes-MIA, Yakutsk and Pierre Auger Observatory data. We analyzed the data of the Moscow State University Extensive Air Shower (EAS–MSU) array on > 10 GeV energy muons in showers caused by ∼ 100 PeV primary particles and demonstrate that they agree with simulations (CORSIKA with QGSJET-II-04, QGSJET-I, EPOS and SYBILL hadronic interaction model) once the primary composition inferred from the surface-detector data is assumed.
