A search for pair production of the lightest supersymmetric partner of the top quark, {tilde t}1, is performed in the lepton+jets channel using 0.9 fb−1 of data collected by the D0 experiment. Kinematic differences between {tilde t}1{bar {tilde t}}1 and the dominant top quark pair production background are used to separate the two processes. First limits from Run II of the Fermilab Tevatron Collider for the scalar top quark decaying to a chargino and a b quark ({tilde t}1 2!{tilde {chi}}1 b) are obtained for scalar top quark masses of 130-190 GeV and chargino masses of 90-150 GeV.

A search for pair production of scalar top (stop) quarks has been performed in the lepton+jets channel in H"1 fb−1 of data at the D0 experiment. Kinematic differences between {tilde t}1{bar {tilde t}}1 and the dominant t{bar t} process are used to separate the two reactions. For stop-quark masses of 145-175 GeV, and chargino masses of 105-135 GeV, to which the stop quarks decay ({tilde t}1 2!{tilde {chi}}1b), we obtain upper limits on the {tilde t}1{bar {tilde t}}1 cross section at 95% confidence, that are a factor of H"7-12 larger than expected from the Minimal Supersymmetric Standard Model (MSSM), as calculated in a next-to-leading-order (NLO) approximation in quantum chromodynamics (QCD).

A search for pair production of scalar top (stop) quarks has been performed in the lepton+jets channel in ̃1 fb-1 of data at the D0 experiment. Kinematic differences between $ar{t}$1$ ilde{t}$1 and the dominant t$ar{t}$ process are used to separate the two reactions. For stop-quark masses of 145-175 GeV, and chargino masses of 105-135 GeV, to which the stop quarks decay ($ ilde{t}$1 → $ ilde{X}$1+b), we obtain upper limits on the $ ilde{t}$1$ar{t}$1 cross section at 95% confidence, that are a factor of ̃7-12 larger than expected from the Minimal Supersymmetric Standard Model (MSSM), as calculated in a next-to-leading-order (NLO) approximation in quantum chromodynamics (QCD).

A search has been performed for scalar top quark pair production in the lepton+jets channel in (almost equal to)1 fb−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 (almost equal to)7-12 higher than expected for the Minimal Supersymmetric Standard Model (MSSM).
