The data selected consist of events characterized by large energy imbalance in the transverse plane and hadronic jets, and no identified electrons and muons, so the sample is enriched in W -> tau nu decays. In order to suppress backgrounds, additional kinematic and topological requirements are imposed through a neural network, and at least one of the jets must be identified as a b quark jet. We measure an excess of signal-like events in agreement with the standard model prediction, but inconsistent with a model without single top quark production by 2.1 standard deviations (sigma), with a median expected sensitivity of 1.4 sigma. Assuming a top quark mass of 175 GeV/c(2) and ascribing the excess to single top quark production, the cross section is measured to be 4.9(-2.2)(+2.5) (stat + syst) pb, consistent with measurements performed in independent data sets and with the standard model prediction.", optnote="ISI:000277201900007", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=287), last updated on Mon, 21 Feb 2011 12:20:39 +0000", issn="1550-7998", doi="10.1103/PhysRevD.81.072003", opturl="http://arXiv.org/abs/1001.4577", opturl="https://doi.org/10.1103/PhysRevD.81.072003", language="English" }
