## Course description

## Objectives and Content

**Objectives:**The course is a continuation of PHYS203 and gives an understanding of the Standard Model of particle physics, which describes the elementary particles and their interactions.

**Content:**The course covers the theories describing the interactions of elementary particles: quantum electrodynamics (QED), quantum chromodynamics (QCD), and electroweak theory. Together, these make up the Standard Model of particle physics. The course gives a basis for calculating and understanding simple cross sections for collisions and particle production. The course also gives a brief introduction to CP violation and neutrino physics.
