Abstract

Wepresent the results of extensive air shower simulations performed with the PYTHIA 8.3 event generator. Custom software has been developed to model the hadronic and muon components of the EAS. The simulation results obtained with PYTHIA 8.3 were compared to those from CORSIKA-77500 by analyzing the longitudinal and transverse muon distributions and the muon energy spectra in the EAS. The influence of free parameters of hadronization model in PYTHIA 8.3 on measurable EAS characteristics was studied. Additionally, EAS simulations were performed under the assumptions of an excess of heavy mesons and t-quarks in hadronic interactions.
