摘要：

We report on a search for standard model t-channel and s-channel single-top quark production in p (p) over bar collisions at a center of mass energy of 1.96 TeV. We use a data sample corresponding to 162 pb(-1) recorded by the upgraded collider detector at Fermilab. We find no significant evidence for electroweak top quark production and set upper limits at the 95% confidence level on the production cross section, consistent with the standard model: 10.1 pb for the t-channel, 13.6 pb for the s-channel and 17.8 pb for the combined cross section of t- and s-channel.
