Searching for new physics scenarios at e⁺e^- linear colliders with polarized beams.
A. A. Pankov and A. V. Tsytrinov

Four-fermion contact interactions can manifest themselves through deviations of observables from the standard model (SM) predictions. We consider a number of such nonstandard scenarios, and discuss their identification as sources of deviations in fermion-pair production processes at the International Linear Collider (ILC) with high energy and time-integrated luminosity L_int=1000fb^-1, respectively, if they were observed. The availability of initial beams longitudinal polarization is also taken into account in the analysis.
Key words: four-fermion contact interactions, fermion-pair production, linear collider
