Original · EN
Selected, recent results, primarily from collider experiments but including some fixed target experiments, are presented as a survey of Quantum Chromodynamics (QCD). The concepts of leading order and next-to-leading order QCD are introduced. Inclusive proton-antiproton jet and dijet production and deep inelastic electron-proton scattering at very large momentum transfer are shown to be in good agreement with perturbative QCD (pQCD). Dijet, three-jet and multi-jet results from proton-antiproton, electron-proton, and electron-electron colliders at moderate Q**2 are also compared to pQCD. BFKL searches from all three colliders are discussed. Recent measurements of structure functions and contributions to the parton distribution functions are presented. New measurements of the strong coupling constant are summarized, the world average is 0.1184 with an uncertainty of 0.0031.
