# R Symmetry

Is there a nice, cute way to see what R symmetry is? I mean, N=1 SUSY has a global $$U(1)_R$$ symmetry, which is a charge carried by the supercharges, right? And a spontnaeously broken $$U(1)_R$$ is a sufficient (but not necessary) condition for broken global SUSY. (Counter-example is O'Raifeartaigh type models with broken SUSY but an intact $$U(1)_R$$.)

Is there anything else that I'm missing, or have I screwed something up?

I'm not sure. I memorized that R-parity odd particles(Pr=-1) are sparticles and R-parity even particles (Pr=+1) are ordinary particles.
Do you mean a model while you'r saying "a cute way" ??

Well, R-symmetry and R-parity are two different things, that are only sometimes related.

I think I just need to read some more of Seiberg's papers. I think he has a set of lecture notes where he outlines this in some more detail.

Could you post references to the Seiberg papers you refere to?
