Extensive air showers rounded up by aires + sibyll/qgsjet

Abstract

An analysis of the differences introduced by the hadronic interaction event generators during the development of the showers is presented. We have generated proton and nuclei induced air showers with energies up to $10^{20.5}$ eV, ``herded up'' by the code aires + sibyll/ qgsjet. The most relevant observables are taken into account for the comparison.
