摘要

The best limit on the strong flavor changing neutral current (FCNC) anomalous couplings was obtained using the direct top production process at the Large Hadron Collider by the ATLAS Collaboration. We perform a similar analysis but using a next-to-leading order generator, MEtop. We then show how the limits could be improved if the FCNC single top process pp -%26gt; tj would be included as signal. Finally we discuss a slightly modified analysis with an extra hard jet in the final state.
