Welcome!

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.

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.  ...

First direct calculation of hadronic light-by-light scattering
Image link

Members of our group have succeeded for the first time in directly calculating the amplitude for hadronic light-by-light scattering on the lattice. Their work, which has appeared in the journal Physical Review Letters, has implications for the theoretical prediction of the anomalous magnetic moment of the muon, which for the hadronic contributions so far has had to rely on phenomenological models.  ...
