Research Topics in CPPS
The two main pillars of the experimental activities in CPPS are the development of novel detectors and the analysis of data from two large experiments, the ATLAS experiment at the Large Hadron Collider (LHC) and the Pierre Auger Observatory, a giant air shower experiment in Argentina. The ATLAS group in Siegen is involved in the operation of the current and the construction of the upgraded pixel detector and the physics of the top quark. At the Pierre Auger Observatory, our focus is on detector electronics and on data analysis concerning cosmic-ray composition and search for ultra-high energy photons. The experimental groups in Siegen are also members of the IAXO, SHiP and LCTPC collaborations.
From the theoretical perspective, we investigate the laws of nature that describe the elementary particles and the forces which describe their dynamics at very small distances/very high energies. Our research deals with conceptual aspects of Quantum Field Theory, with the development of mathematical methods to perform precision calculations within the Standard Model of Particle Physics and its possible extensions, as well as with phenomenological studies of dedicated observables at present or future collider experiments. Among others, we are interested in Heavy Quark Flavours, Quantum Chromodynamics, Higgs Physics, and physics Beyond the Standard Model.
