FYSS4510 Quantum Field Theory (11 cr)
Learning outcomes
At the end of this course, students will be able to quantize spin-0, spin-1/2 and spin-1 free field theories and derive Feynman rules for an interacting field theory from its Lagrange function. Students will be able to compute scattering cross sections for physical processes in the lowest order of perturbation expansion for example in the Yukawa theory and in QED. They will understand well the path integral methods and knows how to use them to quantize both Abelian and non-Abeliand gauge field theories in with differen gauge-choices. They will also understand the basics the renormalization program for scalar theory.
