Beyond the Standard Model

Module code: 901F3
Level 7 (Masters)
15 credits in spring teaching
Teaching method: Lecture
Assessment modes: Open examination, Coursework

This module covers:

  • Basics of global supersymmetry: motivation and algebra, the Wess-Zumino model, superfields and superspace, construction of supersymmetry-invariant Lagrangians.
  • Weak scale supersymmetry: the gauge hierarchy problem, the Minimal Supersymmetric Standard Model (MSSM).
  • Grand unification: SUS(5), the gauge sector, fermion masses, proton decay.
  • Extra dimensions: Kaluza-Klein reduction for scalars, fermions and gauge fields, generation of hierarchies, warped geometry.

Pre-requisite

Level 7: Pre-requisite: (877F3) Quantum Field Theory 1 [T1].
