FYS5120 – Advanced Quantum Field Theory

Teaching and exams spring 2022

In light of the most recent infection control regulations, we will at the start of the spring semester 2022 increase our online teaching, while we at the same time try to maintain in-person teaching where this is possible. We hope to go back to more in-person teaching later on in the semester. You will be informed about any changes in teaching or examinations on the semester page, in Canvas or through your regular channels.

Course content

The main aim of this course is to achieve a modern understanding of quantum field theory, with emphasis on the principles underlying the Standard Model of particle physics. In particular, the course focuses on calculations of radiative corrections (loop diagrams), the understanding of regularisation and renormalisation in quantum field theory, and the quantisation of non-Abelian gauge theories.

Learning outcome

After completing this course, you are expected to

  • be able to carry out one-loop calculations in quantum electro dynamics (QED).
  • explain the origin, interpretation and cancellation of IR divergences.
  • be able to carry out dimensional regularisation.
  • explain the modern interpretation of UV cutoffs and effective field theory (EFT).
  • explain the origin of the renormalisation group, and derive beta functions for running couplings.
  • perform calculations using renormalised perturbation theory.
  • explain how quantisation of a non-Abelian gauge theory differs from that for an Abelian theory.
  • give an account of asymptotic freedom in QCD, and some of its main physical consequences.
  • explain the origin and role of parton density functions.
  • be able to communicate a technical topic in QFT by writing a short review article.

Admission to the course

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

Overlapping courses


  • 2 hours of lectures/sessions per week


  • Project assignment to be handed in on topic agreed upon with lecturer (counts for 40 % of the final grade).
  • Final oral exam (counts for 60 % of the final grade).

It will also be counted as one of the three attempts to sit the exam for this course, if you sit the exam for one of the following courses: FYS9120 – Advanced Quantum Field Theory

Language of examination

The examination text is given in Norwegian. You may submit your response in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.

Facts about this course


If the course is offered, a minimum of four students is required for ordinary lectures to take place. If less than four students participate, an exam will be given, but one should not expect ordinary teaching.
