Measurements of the Cosmic Ray Composition with Air Shower Experiments
Karl-Heinz Kampert,Michael Unger +1 more
TL;DR: In this article, a review of air shower data related to the mass composition of cosmic rays above 10 15 eV is presented, and the analysis of these experimental results in terms of primary mass is highly susceptible to the theoretical uncertainties of hadronic interactions in air showers.
On the knee in the energy spectrum of cosmic rays
TL;DR: In this article, direct and indirect measurements of cosmic rays are reviewed, with emphasis given to the understanding of the knee in the energy spectrum, and the data are compared to contemporary models for the knee.

Constraints from the first LHC data on hadronic event generators for ultra-high energy cosmic-ray physics
TL;DR: The first Large Hadron Collider (LHC) data have extended by more than a factor of three the c.m. energies in which we have direct proton-proton measurements available to compare to hadronic models.
