Light Gluinos and Jet Production in $\bar p p$ Collisions
  The impact of a light, long lived gluino on jet production cross sections in $\bar p p$ collisions is estimated. The effect is found to be relatively modest, particularly when gluinos are incorporated into the parton densities of the proton. Although a light gluino does enhance the production of jets at high $E_T$, the effect is insufficient, by itself, to explain the high $E_T$ excess observed by CDF.
