Abstract:

We examine the effect of an anomalous flavor changing chromomagnetic moment which allows direct top quark production (two partons combining into an unaccompanied single top quark in the s-channel) at hadron colliders. We consider both t-c-g and t-u-g couplings. We find that the anomalous charm quark coupling parameter

\kappa_c / \Lambda

can be measured down to

.06 TeV~{-1}(.009 TeV~{-1}

) at the Tevatron with the Main Injector upgrade(LHC). The anomalous up quark coupling parameter

\kappa_u / \Lambda

can be measured to

.02 TeV~{-1}(.003 TeV~{-1}

) at the Tevatron(LHC).
