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
s(p[`p] ® 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
s(p[`p] ® tb+X, tqb+X) = 3.0 +1.2-1.1 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 paper briefly describes the latest single
top production results from the two experiments.
