Numerous non-standard dynamics are described by contact-like effectiveinteractions that can manifest themselves in electron-positron collisions onlythrough deviations of the observables (cross sections, asymmetries) from theStandard Model predictions. If such a deviation were observed, it would beimportant to identify the actual source among the possible non-standardinteractions as many different new physics scenarios may lead to very similarexperimental signatures. We study the possibility of uniquely identifying theindirect effects of s-channel sneutrino exchange, as predicted bysupersymmetric theories with R-parity violation, against other new physicsscenarios in high-energy e^+e^- annihilation into lepton pairs at theInternational Linear Collider. These competitive models are interactions basedon gravity in large and in TeV-scale extra dimensions, anomalous gaugecouplings, Z' vector bosons and compositeness-inspired four-fermion contactinteractions. To evaluate the identification reach on sneutrino exchange, weuse as basic observable a double polarization asymmetry, that is particularlysuitable to directly test for such s-channel sneutrino exchange effects in thedata analysis. The availability of both beams being polarized plays a crucialrole in identifying the new physics scenario.
