Abstract

The results of a search for direct pair production of scalar top quarks (t̃), the supersymmetric partners of the top quark were presented. Events containing two or more jets and missing transverse energy, the signature of light scalar top quark decays to charm quarks and neutralinos were investigated. 27 events were observed after the selection, while expecting 31.1±6.4 events from known standard model processes. The results were compared to next-to-leading-order production cross sections, and a significant region of t̃ and neutralino phase space was excluded.
