FYS5120 – Advanced quantum field theory
Schedule, syllabus and examination date
The main aim of this course is to achieve a modern understanding of quantum field theory, with special emphasis on the principles underlying the Standard model of particle physics. This includes the importance and interpretation of regularization and renormalization, the geometric structure of gauge theories and functional quantization. The structure of the ground state (the vacuum in particle physics), including its symmetry breaking and excitations (particles), are derived directly from the generating functional (partition function) by using “thermodynamic potentials” borrowed from statistical mechanics. The vacuum structure of abelian (QED) and non-abelian (QCD) gauge theories is analyzed using dimensional regularization. The energy, electrical permittivity and magnetic permeability of empty space explain why the coupling constants (charges) are not constant, and why the magnetic moment of the electron is not given by Dirac’s theory.
Other key words are: path integrals, correlation functions, Wick rotation, Feynman rules, Grassmann calculus, functional determinants, renormalization group, Callan-Symanzik equation, beta-functions, anomalous dimensions, asymptotic freedom, electroweak theory, Goldstone’s theorem, group theory, Higgs mechanism and mixing angles.
The students will be introduced to advanced methods in quantum field theory. Theoretical aspects are more emphasised than applications.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.
