I am also trying to simulate cosmic rays with the version 4.9.3 using the hadronic model QGSP_BERT_HP and electromagnetic model emstandard. Although I obtain reasonable histograms for muons using these models, muon charge ratio (ratio between the number of the antimuons and those of the muons) I acquire at low energy is not consistent with the literature. More over, inconsistency in charge ratio increases when QGSP_BIC_HP model is used.
Are these models convenient for the simulation of the cosmic ray interactions? If they are, is it possible to use them for the interaction of primary protons having energies from 4 GeV to 400 GeV?
Thanks in advance..
