4020130068 Scattering amplitudes in gauge theories
Digital- & Präsenz-basierter Kurs
- classroom language
- DE
- aims
- This advanced topics lectures introduces into modern efficient methods for the computation of scattering amplitudes in gauge field theories. In recent years the traditional Feynman diagram based approach has been challenged by on-shell techniques based on generalized unitarity. The lecture will cover tree-level and one-loop calculations for massless gauge theories with and without supersymmetry. An up to date script will be handed out.
