Light Gluinos
  Gluino and lightest neutralino masses are naturally less than a few GeV if dimension-3 susy-breaking operators are absent from the low energy theory. In this case gaugino masses come from loops and are calculable in terms of known particle masses and two mass parameters, $\mu$ and $\tilde{m}$. The phenomenology of such a scenario is discussed.
