dc.description | The hybrid design of the Pierre Auger Observa tory allows for the measurement of the properties of exten sive air showers initiated by ultra-high energy cosmic rays with unprecedented precision. By using an array of proto type underground muon detectors, we have performed the first direct measurement, by the Auger Collaboration, of the muon content of air showers between 2 × 10^17 and 2 × 10^18 eV. We have studied the energy evolution of the attenuation corrected muon density, and compared it to predictions from air shower simulations. The observed densities are found to be larger than those predicted by models. We quantify this discrepancy by combining the measurements from the muon detector with those from the Auger fluorescence detector at 1017.5 eV and 1018 eV. We find that, for the models to explain the data, an increase in the muon density of 38% ±4%(12%) ±21% 18% for EPOS- LHC, and of 50%(53%) ±4%(13%) ±23% 20% for QGSJetII- 04, is respectively needed. | es |
