PHYS-702 / 4 credits
Teacher: Rattazzi Riccardo
Remark: Next time: Fall
The course builds on the two previous courses on the subject. The main subject is the study of quantum field theories at the loop level. The course introduces the concept of loop divergences and renormalization. Non abelian gauge theories are also discussed in depth.
Skills developed in the course include the use of the Path integral formalism, methodologies to perform loop calculations and renormalization.
1) Path integral approach to QFT
2) Regularization and renormalization
- applications to scalar fields with a quartic interaction
- application to Yukawa theory
- application to Quantum Electrodynamics
3) Non-abelian gauge theories
- BRST quantization
- renormalization at 1- loop
4) The renormalization group
- Callan Symanzik equation
- asymptotic freedom
- fixed points
