Theoretical Physics Department, Fermilab, Batavia, IL 60510(Dated: March 23, 2012)We show that supersymmetric models with a large Dirac gluino mass can evade much of the jetsplus missing energy searches at LHC. Dirac gaugino masses arise from \supersoft" operators thatlead to nite one-loop suppressed contributions to the scalar masses. A little hierarchy betweenthe Dirac gluino mass 5 !10 times heavier than the squark masses is automatic and technicallynatural, in stark contrast to supersymmetric models with Majorana gaugino masses. At the LHC,colored sparticle production is suppressed not only by the absence of gluino pair (or associated)production, but also because several of the largest squark pair production channels are suppressedor absent. We recast the null results from the present jets plus missing energy searches at LHCfor supersymmetry onto a supersoft supersymmetric simpli ed model (SSSM). Assuming a masslessLSP, we nd the strongest bounds are: 748 GeV from a 2j+ /E
