In Regensburg we mainly study "strong" interactions that are described by a nonabelian quantum field theory known as Quantum Chromodynamics (QCD). The most famous and up to now not well understood property of this theory is quark confinement: quarks and gluons only appear within bound states like the proton (so-called hadrons) but have never been observed individually. Thanks to another property of the theory, called asymptotic freedom, quarks and gluons can, however, be "seen" and studied in specially designed experiments (hard reactions) that allow one to look deep inside the proton!

Relating experimental results to fundamental parameters of weak, electromagnetic and new, beyond-the-standard-model interactions requires to compute QCD contributions to these processes, which is our main task.

Some of the areas of our current research are:

FOR 2926 "Next Generation Perturbative QCD for Hadron Structure:

Preparing for the Electron-Ion Collider"

SFB/TR55 "Hadron Physics from Lattice QCD"

Lattice gauge theory

Design of supercomputers for lattice gauge theories

Conformal symmetry in strong interactions

Entropy generation in heavy-ion colisions in AdS/QFT framework

Theory of Hard Exclusive Reactions

High Energy Physics
