Search for s-Channel Single-Top-Quark Production in Events with Missing Energy Plus Jets in p[bar over p] Collisions at √s = 1.96 TeV

The first search for single-top-quark production from the exchange of an s-channel virtual W boson using events with an imbalance in the total transverse energy, b-tagged jets, and no identified leptons is presented. Assuming the electroweak production of top quarks of mass 172.5  GeV/c[superscript...

description The first search for single-top-quark production from the exchange of an s-channel virtual W boson using events with an imbalance in the total transverse energy, b-tagged jets, and no identified leptons is presented. Assuming the electroweak production of top quarks of mass 172.5  GeV/c[superscript 2] in the s channel, a cross section of 1.12[+0.61 over −0.57] (stat + syst) pb with a significance of 1.9 standard deviations is measured. This measurement is combined with the result obtained from events with an imbalance in total transverse momentum, b-tagged jets, and exactly one identified lepton, yielding a cross section of 1.36[+0.37 over −0.32] (stat + syst) pb, with a significance of 4.2 standard deviations.
