FYS9170 – Relativistic quantum field theory

Schedule, syllabus and examination date

Choose semester

Course content

Relativistic field equations. Lagrange formalism. Noethers theorem. Gauge fields. Quantisation of free scalar, vector and Dirac fields. Interacting fields and Feynman diagrams for quantum electrodynamics (QED). Generalisation to non-Abelian theories and electroweak interactions. Functional methods. Higgs mechanism.

Learning outcome

The students get an introduction to relativistic quantum field theory. In particular electroweak interactions between leptons and quarks, and strong interactions between quarks are studied. It is emphasized that the student should be able to perform calculations of typical scattering and decay processes.


PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.


Recommended previous knowledge

It is highly recommended that you have previous knowledge from the following courses:

Overlapping courses

5 credits overlap against FYS303 and FYS381.

10 credits with FYS4170 – Relativistic quantum field theory


The course extends over one full semester with four hours of teaching per week. (lectures and exercises).


Students are required to read chosen articles which will result in an project assignment to be delievered as a lecture before the class.

One home exam counting approximatly 30 % mid semester. An oral exam or written 4-hours final exam counting approximatly 70 % at the end of the semester. The final grade is given as a sum of the two exams. Oral or written exam is decided after registration depending on the number of students who have registered for the exam.

Language of examination

Subjects taught in English will only offer the exam paper in English.

You may write your examination paper in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a pass/fail scale. Read more about the grading system.

Facts about this course






Every autumn

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.
