HEMAS: a Monte Carlo code for hadronic, electromagnetic and TeV muon components in air shower

The features of the HEMAS code are presented. The results of the comparison between the Monte Carlo expectation and the experimental data are shown.

Measurement of the ratio double/single muon events as a function of rock depth with MACRO

We report the measurement by the MACRO experiment of the ratio of double muon events over single muon events as a function of rock depth. Particular attention has been devoted to the analysis of high zenith angle events. Results are compared to the expectation of a detailed simulation performed with HEMAS-DPM Monte Carlo. No deviations with respect to “standard physics” predictions have been fo...
