The enigmatic strong interaction — •Christoph Hanhart — IAS-4, Forschungszentrum Jülich, Jülich

It is the strong interaction that is responsible for forming nuclei, the cores of atoms, by binding protons and neutrons together. The same force, albeit with a quite different mechanism, is also creating protons and neutrons themselves by forming bound states of quarks and gluons. The strong interaction still is the least understood part of the Standard Model*even though the underlying theory, Quantum Chromodynamics (QCD), has been known for several decades. In this presentation the key features of QCD are reviewed and observable consequences presented.

Keywords: strong interaction; confinement; asymptotic freedom; quarks; gluons
