Search for the Supersymmetric Partner of the Top-Quark in $p\bar{p}$ Collisions at $\sqrt{s}=1.8\mathrm{TeV}$

Abstract

We report on a search for the supersymmetric partner of the top quark (stop) produced in $t\bar{t}$ events using $110{\mathrm{pb}}^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}$ recorded with the Collider Detector at Fermilab. In the case of a light stop squark, the decay of the top quark into stop plus the lightest supersymmetric particle (LSP) could have a significant branching ratio. The observed events are consistent with Standard Model $t\bar{t}$ production and decay. Hence, we set limits on the branching ratio of the top quark decaying into stop plus LSP, excluding branching ratios above 45% for a LSP mass up to 40 {\rm GeV/c}${}^2$.
