摘要：

We search for standard model single-top-quark production in the W-gluon fusion and W-star channels using 106 pb(-1) of data from p(p) over bar collisions at roots = 1.8 TeV collected with the Collider Detector at Fermilab. We set an upper limit at 95% confidence level (C.L.) on the combined W-gluon fusion and W-star single-top cross section of 14 pb, roughly six times larger than the standard model prediction. Separate 95% C.L. upper limits in the W-gluon fusion and W-star channels are also determined and are found to be 13 and 18 pb, respectively.
