285130 Quantum Field Theory (V) (SoSe 2026)
Contents, comment
-
Quantum field theory describes all known elementary particles and their interactions except gravity. It reconciles the principles of quantum mechanics with those of special relativity. This course treats the quantization of relativistic scalar, fermion and gauge fields emphasizing the role of symmetries. The relation of the S-matrix, which describes scattering amplitudes, to correlation functions in quantum field theory is derived. We introduce path integrals and use them to do perturbation theory. We obtain the Feynman rules of Quantum Electrodynamics and use them to compute scattering amplitudes.
