Probing QCD at the Highest $Q^2$ Deep Inelastic Scattering

Abstract

Recent results from the HERA ep collider are reviewed in these proceedings. The results are from measurements that probe QCD at high-energy scales, as defined by $Q^2$, the four-momentum-transfer squared of the collisions. These cross-section measurements provide information about the parton distribution functions (PDFs) of the proton and can be used to constrain global fits of these PDFs. Recent measurements of the strong coupling $α_S$ and jet substructure from HERA at similar energy scales are also reviewed.
