High-energy proton cross sections

The measurements of the total, elastic and diffractive proton-proton cross sections at high energies are shown. The article mainly focuses on the recent results of the experiments at the Large Hadron Collider and on the methods and techniques used to perform the measurements. The general properties of the scattering amplitude are also presented, together with the main aspects of some of the most successful theoretical models, whose predictions are compared with the experimental results.
