I teach a one-semester graduate course on (rigid) SUPERSYMMETRY to students attending the Elementary
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.
