Hard Processes in Proton-Proton Collisions at the Large Hadron Collider

Abstract

The measurement of hard scattering processes, meaning those with energy scales of more than a few GeV, is the main method by which physics is being explored and extended by the experiments at the Large Hadron Collider. We review the principal measurements made so far, and what they have told us about physics at the energy frontier.
