Abazov, V. M. and Bertram, Iain and Borissov, Guennadi and Fox, Harald and Ratoff, Peter and Sopczak, Andre (2007) Multivariate searches for single top quark production with the D0 detector. Physical Review D, 75. ISSN 1550-7998Full text not available from this repository.
We present a search for electroweak production of single top quarks in the s-channel (p[overline p]-->t[overline b]+X) and t-channel (p[overline p]-->tq[overline b]+X) modes. We have analyzed 230 pb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider at a center-of-mass energy of sqrt(s)=1.96 TeV. No evidence for a single top quark signal is found. We set 95% confidence level upper limits on the production cross sections, based on binned likelihoods formed from a neural network output. The observed (expected) limits are 6.4 pb (4.5 pb) in the s-channel and 5.0 pb (5.8 pb) in the t-channel.
