Post Doctoral Research Assistant

I joined the Particle Theory group in Autumn of 2015.

My research interests include: Higgs physics, Dark Matter model building, and Beyond the Standard Model phenomenology in general.

I will be teaching Introduction to Symmetries for (experimental) particle physics graduate students in Michaelmas '17.

Information about this course can be found below.

Meeting location and times:
MT'17 weeks 1 to 4 in the Fischer room (examples' class in week 7)

  • Tuesdays 12-1 -- no class on 31.10 but extra class on 7.11 instead (same time).
  • Thursdays 11-12
  • Examples' class: Wednesday 22 Nov. at 14:15

**Extra class** Thursday 9.11 @ 9am in the Fischer room

Content:

  • Spacetime symmetries
  • Internal symmetries (SU(2) & SU(3))
  • Local symmetries (gauge theories and spontaneous breaking)

This course of 8 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.

Strangeness Minus Three
This is an interesting video (BBC Horizon, click above) which aired in 1964 where Murray Gell-Mann, Yuval Ne'eman, and Richard Feynman talk about the prediction and discovery of the \Omega^- baryon (Wikipedia). Gell-Mann (and, independently, Ne'eman) predicted the existence of the \Omega^- to complete the decuplet (10) of flavor SU(3). Not only was its existence predicted, but also its mass. The experimental effort to find it was heroic. It required the analysis of ~97,000 photographic plates.

Lecture notes:
We will essentially follow the notes by Ian Aitchison which are available through http://www.slac.stanford.edu/~aitchiso/ (Introduction to Symmetries).
