Abstract

Information about the strong interaction and its field quanta can be obtained from hadron spectroscopy and, e.g., from deep-inelastic scattering experiments with high-energy muon beams or at the electron-hadron collider HERA. Quarks carry colour charge and form bound systems of colourless mesons and baryons by the exchange of coloured gluons. This interaction leads to scaling violations, i.e., the dependence of the structure functions on the momentum transfer, that are proportional to the strong coupling constant α s . Data from deep-inelastic scattering and hadron-hadron interactions allow the determination of flavour-separated parton distributions. Nuclear effects in deep-inelastic scattering arise due to a modification of the parton momentum distributions by the surrounding nuclear medium.
