Hadron physics and high energy particle physics

Physicists of our faculty of physics and astronomy research (in theory and experiment) the fundamental building blocks of matter with scientific methods.

Finding out about the innermost workings of the universe

Experimental and theoretical physicists in Bonn investigate the fundamental building blocks in the areas hadron physics and high energy particle physics. The experimental groups participate in projects in Bonn (ELSA) and at external research experiments, e.g. CERN or KEK and research bound states of quarks (hadrons) or look for physics effects beyond the standard model of particle physics at the highest energies or in rare hadron decays.  

Theoretical research encompasses a large variety of topics from lattice gauge theory, quantum field theory beyond the standard model all the way to string theory. Models are being developed for the   description of the microcosm. These models are checked for consistency and predictive power.  Predictions of those theories are compared to experimental measurements.

Relevant research institutions

  • CERN is the central European laboratory for particle and accelerator-based research near the town of Geneva in Switzerland. The most important accelerator is currently the large hadron collider (LHC) that started in 2008. Research groups at the University of Bonn participate in the ATLAS and LHC-b experiments.

  • The physics institute has a research cooperation with DESY with a joint professorship in detector development (Jülich cooperative model).

  • The accelerator complex ELSA at the physics institute in Bonn consists of three accelerators (Injector LINAC, Booster Synchrotron and Stretching Ring) and delivers a beam of polarized or un-polarized electrons with adjustable energy up to a maximum 3.5 GeV. For the main research area (hadron physics) a current of several nano-amps can be extracted and guided to several experimental locations.
