MODEL-INDEPENDENT DESCRIPTION OF NEW PHYSICS EFFECTS IN E(-)-](T)OVER-BAR(T)OVER-BAR()E()

We study the potential of a future e(+)e(-) collider for the search of anomalous <gamma t(t)over bar> and Zt(t) over bar couplings, assuming that CP invariance holds. This is done in a model-independent way, co nsidering that all six possible couplings do appear. Two experimental situations are envisaged; with and without e(+/-) beam polarization. O bservability limits in the form of domains in the six-dimensional para meter space are established. illustrations for specific constrained mo dels are also presented and implications for new physics searches are discussed.
