We test the predictions of hadronic interaction models regarding the depth of maximum of air-
shower profiles, X max, and ground-particle signals in water-Cherenkov detectors at 1000 m …

Using corsika simulations, we investigate the mass sensitivity of cosmic-ray air-shower
observables for sites at the South Pole and Malargüe, Argentina, the respective locations of …

The measurement of the flux of muons produced in cosmic ray air showers is essential for
the study of primary cosmic rays. Such measurements are important in extensive air shower …

Here we consider the results of direct measurements of muons in extensive air showers with
zenith angles and energy above eV, obtained at the Pierre Auger Observatory and Yakutsk …

Abstract The Pierre Auger Observatory is the world's largest detector for observation of ultra-
high-energy cosmic rays (UHECRs)(above the energy of $10^{17} $ eV). It consists of a …
