Popis: We investigate the effect of top trilinear operators in t (t) over bar production at the ILC. We find that the sensitivity to these operators largely surpasses the one achievable by the LHC either in neutral or charged current processes, allowing to probe new physics scales up to 4.5 TeV for a centre of mass energy of 500 GeV. We show how the use of beam polarisation and an eventual energy upgrade to 1 TAT allow to disentangle all effective operator contributions to the Ztt and gamma tt vertices.
