Description

Content

Canonical quantization, free scalar field; Greens function and propagator; spin and canonical quantization of free fermion field; symmetries and conservation laws, Noethers theorem, discrete P, C and T symmetries; interacting theories, S-matrix and cross sections, LSZ-reduction; perturbation theory: Wicks theorem and Feynman rules; computing tree level processes, Yukawa theory and QED; path integral methods and generating functions; path integral quantization of gauge theories; renormalization and regularization, canonical and BPHZ-method.

Completion methods

Interactive lectures, assignments, traditional examination, home examination.

Assessment details

The final grade is based on assignments (25-40 %) and examination (75-60 %). The weighting depends on the completion mode.

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.
