Description

Detecting Ultra High Energies Cosmic Rays (UHECRs) enables us to measure the proton-air inelastic cross section $\sigma^{\rm inel}_{\rm p-air}$ at energies that we are unable to access with particle accelerators. The proton-proton cross section $\sigma_{\rm p-p}$ is subsequently inferred from the proton-air cross section at these energies. UHECRs experiments have been reporting on the proton-air inelastic cross section starting with the Fly's Eye in 1984 at $\sqrt s = 30$~TeV and ending with the most recent result of the Telescope Array experiment at $\sqrt s = 95$~TeV in 2015. In this talk, I will present the methods and experimental results from some of these experiment.
