“…The amount of data collected in Run 1 at the Tevatron at a CM energy of 1.8 TeV was not sufficient to accumulate a measurable sample of single top-quark events and only upper limits on the production cross section were set (Abazov et al, 2001;Abbott et al, 2000;Acosta et al, 2002). In Run 2, Tevatron delivered collisions at a CM energy of 1.96 TeV.…”

“…In addition, the LHC has accumulated large amounts of protonproton (pp) collision data at three different CM energies, 7 TeV, 8 TeV, and 13 TeV, while the Tevatron accumulated a large amount of proton-antiproton data at 1.96 TeV. The Tevatron initially collected data at 1.8 TeV, with sufficient statistics to discover the top quark in pair production (Abachi et al, 1995;Abe et al, 1995), but insufficient to measure single top-quark production (Abbott et al, 2000;Acosta et al, 2002).The algorithms for the identification and reconstruction of the so-called analysis objects (e.g., electrons, muons, hadronic jets) are similar though not identical at the different experiments, reflecting their complementary strengths. The focus in single top-quark selections is on identifying isolated high-p T electrons or muons together with large E / T and one or more jets, at least one of which is required to be b-tagged to identify the b quark from the top-quark decay.…”

This paper provides a review of the experimental studies of processes with a single top quark at the Tevatron proton-antiproton collider and the LHC proton-proton collider. Single top-quark production in the t-channel process has been measured at both colliders. The s-channel process has been observed at the Tevatron, and its rate has been also measured at the center-of-mass energy of 8 TeV at the LHC in spite of the comparatively harsher background contamination. LHC data also brought the observation of the associated production of a single top quark with a W boson as well as with a Z boson. The Cabibbo-Kobayashi-Maskawa matrix element |V tb | is extracted from the single-top-quark production cross sections, and t-channel events are used to measure several properties of the top quark and set constraints on models of physics beyond the Standard Model. Rare final states with a single top quark are searched for, as enhancements in their production rates, if observed, would be clear signs of new physics. * andrea.giammanco@uclouvain.be † schwier@pa.msu.edu arXiv:1710.10699v2 [hep-ex] 27 May 2018 13 4. s-channel 13 B.

Moreover, the integrated or differential charge asymmetry in t-channel production provides a powerful input to constrain PDFs, similar to the case of W -boson production, in a region of x B very relevant for several searches. Examples of new physics that might influence t-channel production include a vector-like fourth generation quark with chromo-magnetic couplings (Nutter et al., 2012), a color triplet (Drueke et al., 2015), and FCNC interactions of the top quark with the gluon and the charm quark (Aguilar-Saavedra, 2009a). The s-channel mode is also sensitive to new resonances decaying to a top quark (Drueke et al., 2015), while the tW mode is sensitive to vector-like quarks (Aguilar-Saavedra, 2009b) and resonances decaying to a top quark and a W boson (Nutter et al., 2012). Experimentally, the study of top quarks proceeds by the reconstruction of its decay products. Almost all top quarks decay into a W boson and a b quark (Aaltonen et al., 2013(Aaltonen et al., , 2014aAbazov et al., 2011a; CMS Collaboration, 2014a). The former promptly decays ei...
