SEARCH FOR SINGLE TOP QUARK PRODUCTION AT DØ

    We present a review of searches for electroweak production of single top quarks at the Fermilab Tevatron proton–antiproton collider at . 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.
