In Hilary term 2017, I will be teaching Supersymmetry in the MMathPhys course. Below is some information on the course.

Time and Location:
Tuesdays at 12 noon, Wednesdays at 2pm and Fridays at 11am [Fisher Room]

Textbooks and References:

  • In the past I have co-authored lecture notes which can be found here. Part of the course will follow these notes quite closely.

Let me also list a couple of classic books:

  • S. Weinberg: The Quantum Theory of Fields, Volume III Supersymmetry
  • J. Wess and J. Bagger: Supersymmetry and Supergravity
  • J. Terning: Modern Supersymmetry
  • D. Freedman and A. van Proeyen: Supergravity

A great review on supersymmetry is by Stephen Martin and can be found online:

A concise overview of the Standard Model can be found in this article from Paul Langacker:

Problem sets
There will be three problem sets.

The first, second and third problem sheets can be found here: (1st sheet, 2nd sheet, 3rd sheet).

Introduction to Symmetries

In Michaelmas term 2015, I tought Introduction to Symmetries for (experimental) particle physics graduate students.

Below I there is some information on the lectures.

Time and location: Tue 12-13 and Thu 11-12 (Fisher room, exception: 27th October Seminar room)

Planned content:
- Spacetime symmetries
- Internal symmetries (SU(2) & SU(3))
- Local symmetries (gauge theories and spontaneous breaking)

This course of 7 lectures (plus 1 examples' class) is intended for first year graduate students in experimental Particle and Nuclear Physics. It aims to give an informal introduction to the general subject of symmetries in quantum systems, and to provide the basis for a "practical" knowledge of the most common continuous symmetry groups and their representations, as used in particle physics. The course will assume knowledge of basic non-relativistic quantum mechanics (e.g. hermitian and unitary operators, eigenvalues, constants of motion, degeneracy, spin-½ formalism), of the mathematics of vectors and matrices, and of four-vectors in Special Relativity.

Textbooks: this list might be updated from time to time, it's by no means complete.
