When supersymmetry breaking produces only dimension-2 operators, gluino and photino masses are of order 1 GeV or less. The g∼g bound state has mass 1.3−2.2 GeV and lifetime ≳10− − 10−10 s. This range of mass and lifetime is largely unconstrained because missing energy and beam dump techniques are ineffective. With only small modifications, upcoming K0 decay experiments can study most of the interesting range. The lightest gluino-containing baryon (uds∼g) is long lived or stable; experiments to find it and the uud∼ g are also discussed.
