Search for electroweak single top quark production in ppbar collisions at sqrt{s}=1.96 TeV

TL;DR

This paper searches for electroweak single top quark production in proton-antiproton collisions at 1.96 TeV, setting upper limits on production cross sections due to no significant evidence found.

Contribution

First search for electroweak single top production at Tevatron with specific cross section limits based on 162 pb^{-1} data.

Findings

No significant evidence for single top production

Upper limits set: 10.1 pb (t-channel), 13.6 pb (s-channel), 17.8 pb (combined)

Results consistent with Standard Model predictions

Abstract

We report on a search for Standard Model t-channel and s-channel single top quark production in ppbar 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.
