Search for Single Top Production at the Tevatron

TL;DR

This paper reports on the initial searches for single top quark production at the Fermilab Tevatron using Run II data, setting upper limits on production cross sections without observing evidence of the process.

Contribution

First searches for electroweak single top production at the Tevatron using Run II data, establishing upper limits on cross sections for s-channel and t-channel processes.

Findings

No evidence for single top production was observed.

Upper limits on production cross sections were set for s-channel and t-channel.

Limits vary between the D0 and CDF experiments.

Abstract

Searches for the electroweak production of single top quarks have been started at the Fermilab Tevatron proton-antiproton collider using Run II data by both the D0 and CDF collaborations. Using a dataset of approximately 160pb^-1, neither experiment finds evidence for Single Top production and sets 95% C.L. upper limits on the production cross section. The D0 limits are 19pb on the s-channel production, 25pb on the t-channel production, and 23pb on the combined s+t-channel production. The CDF limits are 8.5pb on the t-channel production and 13.7pb on the combined s+t-channel production.
