Comparison of data from the Pierre Auger Observatory with predictions from air shower simulations: testing models of hadronic interactions

Conferencia; 31st International Cosmic Ray Conference; 2009
The Pierre Auger Observatory is a hybrid instrument that records the longitudinal, lateral and temporal particle distributions of very high-energy air showers and is sensitive to their electromagnetic and muonic components. Such observables depend on energy and on the type of primary particle that initiates the shower and are sensitive to the hadronic interaction properties. Independent analyses of the combined distributions and direct tests of the predictions of hadronic interaction models √s performed are at ≃ 1019 eV, which corresponds to s ≃ 140 TeV for proton primaries.
