If you have a question about this talk, please contact Rose Davies. Scalar quantum electrodynamics (scalar QED ) is the simplest examples of a gauge field theory and gives crucial insight into the link between gauge symmetry and the fundamental forces. We will introduce the concept of a gauge symmetry and use the principle of gauge invariance to write down a toy model for QED . Using this model we will develop a set of Feynman rules, and use them to calculate a scattering amplitude. Finally, we will discuss fermionic QED and non-abelian gauge theories.
