We report on a search for squarks and gluinos in p{anti p} collisions at (square root) s= 1.8 TeV using the D0 detector at Fermilab. Data corresponding to 79.2 " 4.2 pb−1 were examined for events with large missing transverse energy, three or more jets, and the absence of isolated leptons. No events were observed significantly in excess of Standard Model background predictions, and we place limits on the Minimal Supergravity parameters M0 and M12.

We present preliminary results of a search for pair produced top squarks, the supersymmetric partners to the top quark, under the assumption that the two-body decay {bar t}1 --> b{bar W}1 and three-body decay {bar t}1 --> bW{bar Z}1 are kinematically forbidden. This scenario is realized if {bar t}1 is considerably lighter than all other squarks as well as {bar W}1, all {bar v}s, and the top quark. Such light top squarks will dominantly decay via {bar t}1 --> c{bar Z}1 yielding a signal of two acollinear jets with (E){sub T}. The data reported here were taken during the 1992-1993 run of the D0 detector at the Fermilab Tevatron p{bar p} collider operating at (square root)s = 1.8 TeV.
