Cet article offre une revue des résultats importants obtenus au LEP pour tester la validité de la théorie de la chromodynamique quantique (QCD). Les sujets abordés concernent la mesure de αs à partir de la topologie des événements hadroniques, les tests précis de l'indépendence de saveur de αs, des études QCD dans le secteur des quarks lourds, l'étude des différences de fragmentation des jets de quarks et de gluons et l'étude du vertex à trois gluons.

This article gives an overview of the main experimental tests of perturbative QCD performed at LEP. It covers the following topics: determination of αs from event shapes, tests of flavour independence of αs, studies of heavy quark mass effects, differences between quark and gluon jet fragmentation and study of the triple gluon vertex.
