PROBE OF NEW PHYSICS IN TOP-QUARK PAIR PRODUCTION AT E(-)E(+) COLLIDERS

We describe how to probe new physics through examination of the form f actors describing Z-t-tBAR couplings via the scattering process e-e+ - -> ttBAR. We focus on experimental methods on how the top-quark moment um can be determined and show how this can be applied to select polari zed samples of ttBAR pairs through the angular correlations in the fin al state leptons. We also study the dependence on the energy and lumin osity of an e-e+ collider to probe a CP-violating asymmetry at the 10( -2) level.
