87960 - Quantum Field Theory 2

Learning outcomes

The student will become acquainted with perturbation theory for interacting quantum fields and collision theory. In particular, he/she will have a basic knowledge of radiative corrections and vacuum polarization through the use of Feynman diagrams.

Course contents

• Perturbation theory for interacting quantum field theories
• S-Matrix, cross sections and decay rates
• Feynman diagrams and Feynman rules
• Path integrals and generating functionals
• Higher-order corrections, regularization and renormalization
• Quantum electrodynamics (QED)

Exercises will be assigned throughout the course and subsequently discussed and corrected in dedicated lectures.

Assessment methods

Students will be evaluated through a written exam that includes theoretical questions and exercises similar to those addressed during the lectures.

Students with Specific Learning Disabilities (SLD) or temporary/permanent disabilities are advised to contact the University Office responsible in a timely manner (https://site.unibo.it/studenti-con-disabilita-e-dsa/en). The office will be responsible for proposing any necessary accommodations to the students concerned. These accommodations must be submitted to the instructor for approval at least 15 days in advance, and will be evaluated in light of the learning objectives of the course.
