Abstract: This review is focused on the search for new processes, performed with topquark events in D{\O}. It presents four updated or new D{\O} results. The twofirst analyses deal with top production properties: they search for a new heavyresonance decaying to top-antitop. The two last results concern top decayproperties: the measurement of the $W$ helicity as a probe of the $tWb$coupling structure, and the top quark branching ratio to $Wb$. Neither of thesemeasurements reveal any deviation with respect to the standard modelpredictions.
