Research Interests:

Professor Hasenfratz is a high energy theoretical physicist. Her research interest is the study of the properties of quantum field theoretical models like QCD that is believed to describe the strong interactions of elementary particles or the so called Standard Model that describes weak interactions and predicts the existence of the WB1 and Z bosons and the yet undiscovered Higgs particle. The perturbative (small coupling) properties of these models can be studied with standard analytical technics (perturbation theory), but their strong coupling properties are non-perturbative and require a different treatment. Professor Hasenfratz's research concentrates on the non-perturbative properties quantum field theories, mainly QCD. Non-perturbative studies frequently require computer simulations but the emphasis is always on the physical picture and understanding of the physical phenomena.
