dc.description.abstractWe search for the production of single top quarks via flavor-changing-neutral-current couplings of a gluon to the top quark and a charm (c) or up (u) quark. We analyze 230  pb(−1) of lepton+jets data from pp-bar collisions at a center of mass energy of 1.96 TeV collected by the D0 detector at the Fermilab Tevatron Collider. We observe no significant deviation from standard model predictions, and hence set upper limits on the anomalous coupling parameters κ(c)(g)/Λ and κ(u)(g)/Λ, where κg define the strength of tcg and tug couplings, and Λ defines the scale of new physics. The limits at 95% C.L. are κ(c)(g)/Λ<0.15  TeV(−1) and κug/Λ<0.037  TeV(−1).
