The research activities of our group are focused on the development and application of theoretical methods in the physics of strong interactions, the fundamental forces which are responsible for the inner structure of protons and neutrons as well as for the structure of nuclei. The basis of these investigations is Quantum Chromo Dynamics (QCD), the theory of the interaction of quarks and gluons. Part of this program is the investigation of the substructure of baryons and mesons as well as the explanation of the wealth of phenomena resulting from the collective interplay of these particles in nuclei.

The following topics are being investigated:

  • QCD and structure functions: Quark-gluon structure of nucleons and nuclei
  • Low-energy QCD and the physics of hadrons
  • Dense and hot hadronic matter
At high energies, quarks and gluons can be identified as the elementary constituents of hadrons. Structure functions describe the distribution of these quarks and gluons in the interior of nucleons and nuclei. At low energies, the manifestation of the strong interactions is completely different. Condensates of quarks and gluons determine what is going on. In low-energy QCD, the rules for the interplay of these degrees of freedom are dominated by phenomena of spontaneous symmetry breaking. Closely related is a central question of modern nuclear physics: How do the properties of hadrons change in dense and hot matter Extremeforms of compressed hadronic matter exist, e.g., in the interior of neutron stars. They can be created for a very short time in the laboratory in the collision of ultra-relativistic heavy ions.

The above-mentioned projects are being pursued in close contact with experiments at major accelerator facilities, e.g., CERN (Geneva), HERA (Hamburg), GSI (Darmstadt). Our research is supported by funds from BMBF, DFG, GSI, and the Alexander von Humboldt foundation.
Our cooperation agreement with ECT*, the European Centre for Theoretical Studies in Nuclear Physics and Related Fields located in Trento, Italy, offers unique opportunities for diploma and PhD students to benefit from the international research environment at the centre.
