A test of the hadronic interaction model EPOS with air shower data

Abstract

Predictions of the hadronic interaction model EPOS~1.61 as implemented in the\nair shower simulation program CORSIKA are compared to observations with the\nKASCADE experiment. The investigations reveal that the predictions of EPOS are\nnot compatible with KASCADE measurements. The discrepancies seen are most\nlikely due to use of a set of inelastic hadronic cross sections that are too\nhigh.\n
