The CORSIKA 8 project is an international collaboration of scientists working together to deliver the most modern, flexible, robust and efficient framework for simulation ultra-high energy secondary particle cascades in matter. main application cosmic ray air shower simulations, but it can also be applied other problems astro(particle)-physics, physics nuclear physics. Besides a comprehensive s...

The KASKADE and CORSIKA air shower generators are compared to the data collected by MASS2 balloon experiment in 1991. The test of longitudinal profile for proton, helium and muon flux production provide good constraints on these air shower generators. KASKADE and CORSIKA especially with the new simulator UrQMD for low energies are found to fit these data well. This study is limited to a compari...

High-energy neutrino astronomy represents an open window both on astrophysical mechanisms of particle acceleration and on fundamental interactions. The possibility of detecting them in large earth-based apparatus, like AUGER, AMANDA, ANTARES, is quite challenging. In view of this, the capability of generating reliable simulations of air showers induced by neutrinos is mandatory in the analysis ...

While current atmospheric Cherenkov installations consist of only a few telescopes each, future installations will be far more complex. Monte Carlo simulations have become an essential tool for the design and optimisation of such installations. The CORSIKA air-shower simulation code and the sim_telarray code for simulation of arrays of Cherenkov telescopes have been used to simulate several can...

We have generated UHE cosmic ray showers using the CORSIKA program and the QGSJet hadronic interaction code, and have simulated the response of the HiRes detector to the showers. We included in the simulation the triggering and DAQ characteristics of the detector and the background sky noise. We processed these Monte Carlo events with the same analysis program run on HiRes data. To efficiently ...
