Abstract (data abstract)
Fermilab-Tevatron. 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 sets correspond to total integrated luminosities of up to 9.7 fb^{-1} per experiment and were collected during Run II (2001-2011) of the Tevatron collider.
