【 摘 要 】

We present first evidence for the production of single top quarks at the Fermilab Tevatron p(bar p) collider. Using a 0.9 fb(sup -1) dataset, we apply a multivariate analysis to separate signal from background and measure cross section for single top quark production. We use the cross section measurement to directly determine the CKM matrix element that describes the Wtb coupling. We also present results of W0 and charged Higgs searches with the same final states as standard model single top quark production.
