 P: 4 Thank you for your help, but its only half the truth (I've figured it out myself this morning). You're right, its the F-Term, but its only a tricky way writing it. If you take the $$\Phi$$ you suggested, and construct a polynom out of different $$\Phi_i$$'s and then only take terms of the Order $$\theta_L^2$$ you get my Term. To see this, take only the $$\phi$$-Terms of the polynom but either two of the $$\psi$$'s, or one $$F$$. So all terms are of the order $$\theta_L^2$$. If you now count the possibilities of replacing one of the possibilities $$\phi$$'s with a $$\psi$$ (two times, so you get two $$\theta$$), you get same factor as if you just take the whole polynom in $$\phi$$ and derive in respect to $$\phi$$. Thats the whole trick in there. You are right, I'm jsut learning SUSY, but Weinbergs is the best book I could find. In my opinion, all the other books are too brief or just incomplete, including Argyres or Wess and Bagger. And you're right, Weinberg is a hard text, but at least he gives enough motivation to the things he does. I'm only missing some comments here and there. So if you know a script (other than Argyres. I got this one.) somewhere, based on Weinbergs Book with some extra remarks and comments, that would be great. And yeah, this is a students presentation. 5 weeks to go. And again, thank you for your help. Eisenhorn
