Abstract
The Pierre Auger Observatory is the largest extensive air shower detector. Based on a hybrid system, this experiment measures the longitudinal shower development and the particles at the ground. This detection system allows the extraction of the p-air cross-section at energies much higher than the ones accessible by current colliders. It is also possible to test hadronic interaction models using correlations between different air shower observables, like the depth of shower maximum and the muon number at the ground and their fluctuations. Thanks to the low energy extension of the Pierre Auger Observatory, the muon deficit in air shower simulations can be addressed over almost three decades at the highest energies.

Report
Nice summary of important results on cosmic ray physics from the Pierre Auger observatory.
The only suggestion is that perhaps it would be good to clarify whether the sqrt(s) mentioned for the p-air cross section is per nucleon (as is often the convention in high-energy ion beam experiments) or total.
