This does really help, thank you!
Do you also know, what the R-symmetry in this case has to do with the F-term in the SUSY Lagrangian? If I remember correctly, the F-term is some sort of mass term, isn't it? Or it could lead to a mass term, if we break SUYS?
I have somehow this picture...
Hi,
I have forgotten all about my supersymmetry knowledge and all about my group theory knowledge. I am trying to understand what the R-symmetry in N=4 U(N) SYM does. Sadly I have never actually learned anything about supersymmetry which is larger than N=1. I know the R-symmetry is SU(4) and...
