Search for Single-Top-Quark Production in p-pbar Collisions at sqrt(s)=1.8 TeV

TL;DR

This paper reports a search for single-top-quark production in proton-antiproton collisions at 1.8 TeV, setting upper limits on production cross sections that are above standard model predictions.

Contribution

First search for single-top-quark production at Tevatron energies using specific channels, establishing upper limits on cross sections.

Findings

Upper limit on combined cross section: 14 pb

Separate limits: 13 pb (W-gluon fusion), 18 pb (W* channel)

Limits are roughly six times the standard model prediction

Abstract

We search for standard model single-top-quark production in the W-gluon fusion and W* channels using 106 pb^-1 of data from p-pbar collisions at sqrt(s)=1.8 TeV collected with the Collider Detector at Fermilab. We set an upper limit at 95% C.L. on the combined W-gluon fusion and W* 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* channels are also determined and are found to be 13 and 18 pb, respectively.
