Master thesis in Particle Physics

If you are interested in a Master thesis in theoretical particle physics,
you should have successfully participated in the lecture courses Theory of
Relativity and Cosmology and Quantum Field Theory 1 and 2 including the
problem classes. Participation in the lecture course Relativistic Quantum
Theory (at the bachelor level) is highly recommended.
