Spatial distribution of muons in extensive air showers: experiment, calculations

Investigations regarding the spatial distribution of the muons, possessing an energy of more than 10 GeV, have been carried out in the extensive air showers (EAS) at the sea level. The experiment has been staged at the Moscow State University complex installation. The experimental data are compared with the computations carried out for the various models of the hadronic interactions. At the same time it was supposed that the EAS were generated by the primary protons and that the value of the average transverse momentum of the secondary particles was equal to 0.4 GeV/s. It has been shown that the theoretical results are consistent with the experimental data
