Search for -Channel Single-Top-Quark Production in Events with Missing Energy Plus Jets in Collisions at
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 2 in the s channel, a cross section of 1.1 2 $$+ 0.61\atop{- 0.57}$$ ( 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 1.3 6$$+ 0.37\atop{- 0.32}$$ ( stat + syst ) pb, with a significance of 4.2 standard deviations.
