We study the strong interaction at low and medium energies. Our activities focus on the theoretical interpretation of the experiments at MAMI and at other accelerator facilities. Beside analytical methods like effective field theories and dispersion theory numerical simulations of Quantum Chromodynamics on the lattice are applied.

Strong interactions at neutron-rich extremes

The strong force, described by quantum chromodynamics (QCD), is one of the four fundamental interactions of nature. It gives rise to the formation of hadrons and nuclei that constitute the baryonic matter in the Universe, and governs the densest matter in neutron stars and highest temperatures reached in compact object mergers. However, big science problems of QCD remain unsolved, regarding the origin of heavy elements in the Universe, and the structure of extreme neutron-rich matter in the laboratory and in neutron stars. The Facility for Antiproton and Ion Research (FAIR) will discover over a thousand new isotopes, getting as close as possible to the nuclei in the Universe's heavy-element nucleosynthesis pathway, the r-process. On the theoretical side, there are impressive advances towards a unified description of all nuclei and matter based on effective field theories of QCD. In this talk, we will discuss the advances, status and challenges in understanding strongly interacting matter at neutron-rich extremes in the laboratory and the cosmos...

Workshop "New Vistas in Low-Energy Precision Physics (LEPP)"
Image link

The aim of this workshop is to discuss the physics opportunities at MESA, especially the opportunities given at the internal target experiment MAGIX. At MAGIX, the combination of a windowless target in combination with a high-intensity energy-recovering electron beam opens the avenue for new precision measurements in the fields of nuclear, hadron, and particle physics.  ...
