The Standard Model

At the Tevatron Collider it is possible to create single top quarks in the final state via either off mass shell W production (W*), or the W-gluon fusion process. The Standard Model predicts a production cross section of only a few picobarns. In addition, the backgrounds for single top production at large. The datasets collected during Run I at the Tevatron were not sufficiently large to extract the signal from the large W+jets background. In Run II at the Tevatron, we expect to collect 2 fb -1 of data, a twenty fold increase. We present here a method of searching for single top production using the Artificial Neural Network technique. We will describe the technique and present results based on Monte Carlo studies. We will demonstrate that the Neural Net approach is well suited for extracting the signal from a sample with a poor signal-to-background ratio.

We present a review of searches for electroweak production of single top quarks at the Fermilab Tevatron proton–antiproton collider at [Formula: see text]. Searches for s-channel and t-channel single top quark production have been carried out using secondary-vertex b-quark tagging and advanced event analysis methods in order to maximize the sensitivity to single top quark production. So far, no evidence for a single top quark signal has been found. However, 95% confidence level upper limits on the production cross-section have been set that improve upon previous limits by factors of two to three and are approaching the cross-section region predicted by the standard model.

We present a search for the electroweak production of single top quarks using 156-169 pb-1 of electron+jets data collected by the DØ detector, at [Formula: see text], at the Tevatron proton-antiproton collider at Fermilab. In the absence of any significant evidence for single top production we set upper limits on the cross section at 95% C.L., of 14 pb for s-channel, 20 pb for t-channel, and 18 pb for the combined s + t channel.
