Abstract: (Elsevier)

We present a search for the pair production of scalar top quarks ( t˜1 ), the lightest supersymmetric partners of the top quarks, in pp¯ 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 D0 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˜¯1→bb¯μτν˜ν˜ and t˜1t˜¯1→bb¯ττν˜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.
