Additional Support

The single top quark production has an electroweak nature and provides an additional support to the top pair production source of the top quarks. The processes involving single top have unique properties and are very interesting from both theoretical and experimental viewpoints. Short review of the single top quark production processes is given in the paper.

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.

Production Modeling

There are no experimental bounds for the anomalous Wtb couplings provided in the tW-associated single top quark production in the final signature with lepton plus jets so far. The main reason for the situation is the difficulties with the modeling of such a process. Different schemes of the tW-associated single top quark production modeling have different sensitivity to the anomalous Wtb couplings and prospective their constraints are strongly scheme-dependent. The most preferable is the usage of the full gauge-invariant set of the diagrams. However one needs to discriminate the different phase space regions in this case anyway. In the article the separation between top pair and tW-associated single top quark production processes with the help of Neural Network technique is presented. The full scheme with the complete gauge invariant set of Feynman diagrams is used.

In the proton–antiproton collisions at Fermilab, individual top quarks are expected to be produced by an electroweak mechanism referred to as single-top-quark production. In this paper we review the CDF results of the search for single-top-quarks, along with the prospects for the current collider run.

This paper summarizes top quark cross-section measurements at the Tevatron and the LHC. Top quark pair production cross-sections have been measured in all decay modes by the ATLAS and CMS collaborations at the LHC and by the CDF and D0 collaborations at the Tevatron. Single top quark production has been observed at both the Tevatron and the LHC. The t-channel and associated Wt production modes have been observed at the LHC and evidence for s-channel production has been reported by the Tevatron collaborations.
