Our Particle Physics Groups theme to understand the fundamental building blocks of matter and how they interact with each other. Our researchers are actively involved in both, theoretical and experimental physics. The experimental groups are currently involved in two experiments based at the Large Hadron Collider at CERN, CMS and LHCb. We also develop novel detector technologies, and actively participate in the development of next-generation of proposed experiments, such as SHIP and FCC. Theoretical groups work on precision calculations in QCD and electroweak theory, flavour physics and new theories beyond the Standard Model.
