The search for the electroweak production of top quarks is entering an exciting time: with the ever increasing luminosity furnished by the Tevatron $$p \bar p$$ Collider at Fermilab and sophisticated analysis techniques we are now able to approach the expected standard model production cross section for this new mode of production. Using 370 pb^-1 of DØ data and likelihoods as discriminants to extract the signal from the large backgrounds, we set upper limits on the standard model production cross section in the s-channel of 5.0 pb and in the t-channel of 4.4 pb, at 95% confidence level.
