In theoretical particle physics, the fundamental interactions of the elementary building blocks of nature are investigated by calculating predictions for experimental quantities based on well-founded models and theories.

The research interests of the various research groups include precision calculations of hadron and lepton colliders, Higgs boson physics, top quark physics, flavor physics, strong and weak interactions, dark matter, electroweak baryogenesis, neutrino physics, light new particles, supersymmetry, and the development and application of new methods in perturbation-theoretic quantum field theory and cosmology.

The central lectures in the Theoretical Particle Physics subject area are Theoretical Particle Physics I and II, in which the fundamentals of quantum field theories are taught and important applications are discussed.

In addition, there is a wide range of special lectures in which individual aspects are treated in depth. These include lectures on effective theories, collider physics, colourful loops, selected topics of the Standard Model, flavor physics, neutrinos, physics beyond the Standard Model, dark matter, and many more.

Most lectures are accompanied by exercises in which the mathematical methods are applied to numerous practical examples. The exercises offer a first insight into the working methods of theoretical particle physics and are thus an optimal preparation for a master thesis.

In the Hauptseminar you have the opportunity to familiarize yourself with a current research topic in the context of a lecture.
