On March 4, 2009, the DØ and CDF collaborations at Fermilab's Tevatron Collider submitted papers to Physical Review Letters announcing observation of single top quark production.1,2 This review paper describes the successful searches carried out independently by the two collaborations, allowing the reader to see the similarities and differences that led to the simultaneous discoveries. Both collaborations measured a cross section [Formula: see text] consistent with the standard model prediction at 5.0 standard deviation significance, and set a lower limit on the quark mixing matrix element |Vtb| without assuming matrix unitarity with three quark generations.

This paper discusses a search for electroweak production of single top quarks in the electron+jets and muon+jets decay channels. The measurements use ≈ 90 pb -1 of data from Run 1 of the Fermilab Tevatron collider, collected at 1.8 TeV with DØ detector. We use events that include a tagging muon, implying the presence of a b jet, to set an upper limit at the 95% confidence level on the cross section for the s-channel process [Formula: see text] of 39 pb. The upper limit for the t-channel process [Formula: see text] is 58 pb.
