Module code: 878F3
Level 7 (Masters)
15 credits in autumn semester
Teaching method: Workshop, Lecture
Assessment modes: Unseen examination, Coursework

The module provides an introduction into group theory and aspects of symmetry in particle physics, covering:

  • Groups and representations
  • Lie groups and Lie algebras
  • Space-time symmetries and Poincare group
  • Symmetry and conservation laws
  • Global, local, and discrete symmetry
  • Symmetry breaking and the origin of mass
  • Symmetry of the standard model, CKM matrix, neutrino masses, tree-level interactions.

Module learning outcomes

  • Show an understanding of the concepts underlying symmetry such as Lie algebras and their representation.
  • Understand how these concepts are realized in a field theory.
  • Appreciate the consequences of symmetry, and symmetry-breaking, in the Standard Model of particle physics.
