[en] Quantum chromodynamics (QCD), although almost twenty years old, has yet to be satisfactorily proved and completed. Yet it continues to be a cornerstone of particle physics as the only serious contender to explain the strong nuclear force and is the basis against which particle collision experimental results are compared. The author seeks to assess QCD by comparing its predictions with results from new experiments, new accelerators and the latest supercomputers. Several key issues remain unresolved, confinement still needs to be proved (despite some encouraging work on lattice QCD research), the non-perturbative issue and the absence of a definitive experimental test for the theory.
