Kort om emnet

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.

Hva lærer du?

The students will be introduced to advanced methods in quantum field theory. Theoretical aspects are more emphasised than applications.

Opptak og adgangsregulering

Ph.d.-kandidater ved UiO søker plass på undervisningen og melder seg til eksamen i Studentweb.

Hvis emnet har begrenset kapasitet, vil ph.d.-kandidater som har emnet i sin utdanningsplan ved UiO bli prioritert. Noen nasjonale forskerskoler kan ha egne regler for rangering av søkere til emner med begrenset kapasitet.

Ph.d.-kandidater som har opptak ved andre utdanningsinstitusjoner må innen angitt frist søke om hospitantplass.
