We report the first observation of single top quark production using ppbar collision data with sqrt{s}=1.96 TeV collected by the CDF II and D0 detectors at Fermilab. The significance of both the observed CDF and D0 data is 5.0 standard…

We present first evidence for the production of single top quarks in the D0 detector at the Fermilab Tevatron ppbar collider. The standard model predicts that the electroweak interaction can produce a top quark together with an antibottom…
