Resumen:
We present a search for electroweak production of single top quarks in the s-channel (p p ! tb X)and t-channel (p p ! tqb X) modes.We have analyzed 230 pb1 of data collected with the D0 detectorat the Fermilab Tevatron Collider at a center-of-mass energy of p s 1:96 TeV. No evidence for a singletop 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 are6.4 pb (4.5 pb) in the s-channel and 5.0 pb (5.8 pb) in the t-channel.
