Supersymmetry is easy, isn't it?. I have posted (in spanish) a brief introduction to the subject. And I'll make more posts abut it. I am almost sure that everyone who has passed a course in QFT can understand the basics of supersymmetry.

After all, you have a superpartner for every particle, that has opposite statistic. You have funny names for the superpartnerts. The partner of the electron is the slectron, the quark has the squark, etc. And for bosonoics fields the thing is easy also. To the photon corresponds the photino, to the gluons the gluino, to the higgs the higssino, etc.

Well, them if you remember that for every broken global symmetry there is an associated particle, the goldstone boson them you know what a goldstino is. Isn't it?

Well, if you read the book that gives title to the entry(the full title is theory and phenomenology of sparticles) you will realize that maybe the goldstino could not be exactly what you think.

And, of course, you will learn a lot more about phenomenology of N=1 supersymmetry in 4 dimensiones. That includes the MSSM, cosmology of supersymmetry models, etc, etc. The books is from 2004 (reprinted in 2007) so it is, I guess, terribly outdated. I find it a lot better option that the,somewhat similar in it's purpose, book of Michel Dine (supersymmetry and superstrings). Ok, this book doesn't cover superstring, and it has many more pages. But with the actual trend of growing interest in phenomenology, motivated by the dark matter experiments, and the beginning of operation of the LHC it looks as a good reference book to get good info about the characteristics of neutralino, methods of supersymmetry breaking or whatever.

P.S. I'll try o update the previous posts, as promised, as soon as possible.
