摘要: A search has been performed for scalar top quark pair production in the lepton+jets channel in {approx}1 fb{sup -1} of data. Kinematic differences between the exotic stop-stopbar and the dominant ttbar process are used to separate the two possible contributions. For scalar top quark masses of 145-175 GeV and chargino masses of 105-135 GeV we obtain upper cross section limits at 95%confidence level for stop-stopbar production that are a factor of {approx}7-12 higher than expected for the Minimal Supersymmetric Standard Model (MSSM).
