Matteo Bertolini: Lectures on Supersymmetry

Supersymmetry    Gauge/String Correspondence
 Every particle has its partner... (from CERN site) " Darn! Almost got it!"       -- Albert Einstein

I teach a one-semester graduate course on (rigid) SUPERSYMMETRY to students attending the Theoretical Particle Physics PhD curriculum at SISSA. Below you can find the index of the topics discussed, a big file containing the full set of lectures as well as separate pdf files for each lecture.

Disclaimer. These notes are rather preliminary in many aspects, and permanently work in progress. Moreover, there might be many small mistakes and typos. I hope to be able to improve them in the near future. Any suggestions or comments in this direction are most welcome.
