SUSY Breaking and Light Gauginos

Several supersymmetry breaking mechanisms do not produce dimension-3 operators. I show here that this scenario is consistent with present observations and has several significant virtues: i) When there are no dimension-3 SUSY-breaking operators there is no SUSY-CP problem. ii) SUSY-breaking need not occur through gauge singlets, so that the cosmological problems often encountered in hidden sector SUSY-breaking can be avoided. iii) Photino and gluino and $R$-hadron masses are naturally consistent with relic photinos providing the required dark matter density. Requiring spontaneous electroweak symmetry implies that scalar masses are mostly in the $\sim 100$ GeV range. The gluino and photino are massless at tree level. At 1-loop, the gluino and photino masses at the ew scale are predicted to be $m_{\gluino}\sim 10 - 600$ MeV and $m_{\photino} \sim 100 - 1400$ MeV. New hadrons with mass $\sim 1 \frac{1}{2}$ GeV are predicted and described. The ``extra'' flavor singlet pseudoscalar in the $ι(1440)$ region which has been observed in several experiments is naturally interpreted as the mainly-$\gluino \gluino$ bound state which gets its mass via the QCD anomaly. Its superpartner, a gluon-gluino bound state, would be the lightest $R$-hadron. For the most interesting portions of parameter space the $R^0$ lifetime is $10^{-6} - 10^{-10}$ sec, so existing searches would not have been sensitive to it. Search strategies and other consequences of the scenario are briefly mentioned.
