Abstract:
A Monte Carlo program, based on GEANT and using GHEISHA at energies
below 30 GeV, is developed for simulation of the hadron and muon
components of extensive air showers with primary energy 10^12-10^17 eV.
Calculations of the characteristics of multi-muon events as observed
underground by the LEP detectors are presented and their dependence on
the primary cosmic ray composition and some basic assumptions of the
hadronic interaction model is discussed.
