Title: Search for Scalar Top
Abstract: We report results of three searches for scalar top quark. Two of the searches look for direct production of scalar top quark followed by the decay of the scalar quark to charm quark and neutralino or bottom and chargino. The third search looks for top quark decaying to scalar top and neutralino followed by the decay of scalar top to bottom quarkand neutralino. We find no evidence for the presence of scalar top quark in any of the searches. Therefore, depending on the search we set limits on the production cross-section, ${\mathcal BR}(t \rightarrow \tilde{t}_1 + \tilde{\chi}_{1}^{0})$, or $m_{\tilde{t}}$ vs.\$m_{\tilde{\chi}_{1}^{0}}$.
