Abstract
The influence of high and low energy hadronic models on lateral distribution functions of cosmic ray air showers for AUGER energies is explored. A large variety of presently used high and low energy hadron interaction models are analysed and the resulting lateral distribution functions are compared. We show that the slope as well as the signal at 1000 m distance from the shower axis depend on both the high and low energy hadronic model used. The models are confronted with available hadron-nucleus data from accelerator experiments.
