A hadronic interaction plays an important role in air shower development, and the detailed understanding is a key to understand the mass composition.
The diffractive collision is one of the proposed sources of the uncertainties of air shower predictions. In this work, we investigate how the difference in the diffractive collision treatment between models affects the depth of the maximum of...
In the sub-TeV regime, popular hadronic interaction models disagree in their predictions for post-first interaction and ground-level particle spectra. These model differences generate a significant source of inherent uncertainty in their experimental utilization.
We investigate the nature and impact of such differences through a simultaneous analysis of ground level particles and first...
We will report about the optimization work done so far on CORSIKA 7 for the use case of CTA. We will present in particular how we have applied vectorization techniques to the Cherenkov module obtaining a speed-up of almost a factor 2.
