Measurement of the Muon content of Extensive Air Showers with the Pierre Auger Observatory
arXiv:1505.05527
Abstract
Several methods developed within the Pierre Auger Collaboration for the estimation of the muonic component of the Extensive Air Showers observed in the surface Cherenkov detectors are described. The results derived from the data show a deficit of muons predicted by the current hadronic interactions models at ultra-high energies.
