Chair of Particle Physics and its Simulation
Our group works at the interface between experiment and theory: both on the experimental investigation of the symmetries of the "Standard Model of Particle Physics" with the ATLAS detector and on the theoretical simulation of LHC collisions with the Sherpa simulation program.
The Higgs field as a shock absorber in scattering experiments at CERN
We are studying some of the rarest but most important processes at CERN's Large Hadron Collider (LHC), the scattering of W and Z particles off each other.
To observe this, two quarks in the proton-proton collisions at the LHC must each emit a W or Z at the same time by chance, and these must then come closer to each other than 1/1000 of a proton diameter. The Brout-Englert-Higgs field plays an important role here as a kind of "damper", and thus the properties of the Higgs boson can also be investigated.
Through our research into the scattering of W and Z bosons at the ATLAS experiment as part of the BMBF core research areas FSP-ATLAS, we can not only check whether the contribution of the Higgs particles damps the scattering exactly as predicted, but we are also measuring the so-called "quartic vertex" between four bosons for the first time, a completely new chapter in the Standard Model.

Theoretical simulation of LHC collisions with Sherpa
Our group also works on the theoretical simulation of LHC measurements. We are mainly concerned with the calculation of QCD effects using Monte Carlo simulation, and with ATLAS measurements that are sensitive to the modeling aspects of this simulation. We play a major role in the development of a widely used simulation program called Sherpa.
