Theoretical elementary particle physics is dealing with the laws of the fundamental forces, like the electromagnetic, the weak and the 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. Our research plays a crucial role for the interpretation of the particle accelerator experiments performed at DESY and elsewhere. Current activities of the Theory Group at DESY Zeuthen 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. In particular the non-perturbative investigation of QCD on a lattice requires enormous computer resources.
