Description

Measurements of ep collisions at HERA which probe and constrain QCD are presented from the H1 and ZEUS Collaborations. The HERA combined measurements of the inclusive deep inelastic scattering cross sections provide the strongest constraint of the structure of the proton. High-precision jet cross sections are presented which allow a world-competitive measurement of the strong coupling constant. The structure of the proton is also constrained through measurements of heavy-quark production which are sensitive to the gluon and heavy-quark content of the proton; the measurements also allow extractions of the heavy-quark masses. The nature of diffractive processes is still poorly understood and new measurements both in inclusive and exclusive final states aim to shed more light on the subject. A review of the current status of probes of QCD at HERA will be presented and open issues highlighted.
