Single Top Quark Production at the Fermilab Tevatron Collider

First evidence for single top quark production has recently been found by both the D0 and CDF experiments. By combining three analyses, D0 measured a cross section of σ (pp̄ → tb+X, tqb+X) = 4.7± 1.3 pb, with a significance of 3.6 standard deviations, and CDF’s matrix elements analysis measured a cross section of σ (pp̄ → tb+X, tqb+X) = 3.0 −1.1 pb, with a significance of 3.1 standard deviations. These analyses also provided the first direct measurements of the CKM matrix element, |Vtb|, without assuming unitarity. This talk briefly describes the latest single top production results from the two experiments.
