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\u2009\u2009fb 121 per experiment. The measured cross section is \u3c3s=1.29+0.26 120.24\u2009\u2009pb. The probability of observing a statistical fluctuation of the background to a cross section of the observed size or larger is 1.8 710 1210, corresponding to a significance of 6.3 standard deviations for the presence of an s-channel contribution to the production of single-top quarks
