David Tong: Lectures on Supersymmetry
This is a course of supersymmetric field theory given to Part III (i.e. masters level) students. It covers the basics of supersymmetric field theories, as well as more advanced topics such as Seiberg duality. Please do email me if you find any typos or mistakes.
