R-Symmetric Gauge Mediation
September 30, 2008

We present a version of Gauge Mediated Supersymmetry Breaking which
preserves an R-symmetry---the gauginos are Dirac particles, the A-terms
are zero, and there are four Higgs doublets.  This offers an alternative
way for gauginos to acquire mass in the supersymmetry-breaking models of
Intriligator, Seiberg, and Shih.  We investigate the possibility of using
R-symmetric gauge mediation to realize the spectrum and large sfermion
mixing of the model of Kribs, Poppitz, and Weiner.
