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.
