Abstract
We report the first observation of single-top-quark production in the
s
channel through the combination of the CDF and D0 measurements of the cross section in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV. The data correspond to total integrated luminosities of up to
9.7
fb

1
per experiment. The measured cross section is
σ
s

. The probability of observing a statistical fluctuation of the background to a cross section of the observed size or larger is

, corresponding to a significance of 6.3 standard deviations for the presence of an
s
-channel contribution to the production of single-top quarks.
