SAGEX role: beneficiary

DESY is one of the world’s leading accelerator centres. Researchers use the large-scale facilities at DESY to explore the microcosm in all its variety – from the interactions of tiny elementary particles and the behaviour of new types of nanomaterials to biomolecular processes that are essential to life. The accelerators and detectors that DESY develops and builds are unique research tools. The facilities generate the world’s most intense X-ray light, accelerate particles to record energies and open completely new windows onto the universe.

DESY Theory Group

The DESY Theory Group is a leading centre for Theoretical Physics in Europe. It carries out an active research programme on the fundamental interactions of nature and the fabric of matter, space and time. The research in particle theory is closely linked with the experimental research in particle physics at DESY by explaining observations and making predictions for future experiments.

Elementary Particle Theory Group, Zeuthen

Theoretical elementary particle physics deals with the laws of the fundamental forces, such as the electromagnetic, weak and strong interaction forces, and with the structure of the elementary particles. The framework of elementary particle theory is quantum field theory, in particular, the Abelian and non-Abelian gauge theories. The research of the Elementary Particle Theory Group, Zeuthen plays a crucial role for the interpretation of the particle accelerator experiments performed at DESY and elsewhere.

Current activities concern phenomenology of high energy processes, electroweak theory, perturbative and non-perturbative Quantum Chromodynamics (QCD). Calculations are performed analytically as well as with high performance computers.
