The theory group studies 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. We use both analytical methods like effective field theories and dispersion theory, and numerical simulations of nuclear structure and of Quantum Chromodynamics on the lattice.

25th European Conference on Few-Body Problems in Physics
The 25th European conference on few-body problems in physics (EFB25) was held in Mainz, Germany, from July 30th to August 4th, 2023. Like previous conferences in this series, this conference was devote to the presentation and discussion of recent developments in the field of few-body systems, i.e., systems which can be understood in terms of a few degrees of freedom.This Conference focused on recent developments in the field of few-body systems in the areas of hadron physics, nuclei and hypernuclei, electroweak processes, nuclear astrophysics, cold atoms and quantum gases, atoms and molecules, as well as few-body methods and few-body aspects of many-body systems ...

Doctoral Dissertation Completed
This thesis is dedicated to the dispersion relation approach, which is built upon the unitarity and analyticity properties of the scattering matrix. We apply it to study the pion-pion and pion-kaon scattering, in which the lightest scalar resonances show up. The knowledge of the pion-pion amplitude allows us to perform an analysis of the double-virtual photon-photon scattering to two pions, which contributes to the hadronic light-by-light scattering part of the anomalous magnetic moment of the muon. We also consider the two photon fusion reaction with D-meson pair in the final state, which is expected to contain two charmonium resonances ...
