    We present a search for the pair production of scalar top quarks (t˜1), the lightest supersymmetric partners of the top quarks, in ppˉ collisions at a center-of-mass energy of 1.96 TeV, using data corresponding to an integrated luminosity of {7.3 fb−1} collected with the /dzero experiment at the Fermilab Tevatron Collider. Each scalar top quark is assumed to decay into a b quark, a charged lepton, and a scalar neutrino (ν˜). We investigate final states arising from t˜1t˜1ˉ→bbˉμτν˜ν˜ and t˜1t˜1ˉ→bbˉττν˜ν˜. With no significant excess of events observed above the background expected from the standard model, we set exclusion limits on this production process in the (mt˜1,mν˜) plane.
