Abstract:
Quantum Chromodynamics (QCD) is the gauge field theory of the Strong Interaction, one of the four fundamental forces in nature, which is binding quarks and gluons inside hadrons and nucleons inside atomic nuclei. The strong binding force is also responsible for generating almost all the mass of hadronic matter that makes up our visible universe. Specific features of QCD, such as "Confinement", "Asymptotic Freedom" and - equivalently - the effect of gluon self coupling, provide firm predictions for precision tests of this theory. In this seminar, basic features of the theory and the status of experimental tests of Asymptotic Freedom and other features of QCD are reviewed.
