Comparative Study of Contact Interaction Searches in e⁺e^- and e^-e^- Scattering at a Polarized Linear Collider
A.A. Pankov

We study four-fermion contact-interaction searches in the processes e⁺e^- e⁺e^-, µ⁺ µ^- and e^-e^- e^-e^- at planned Linear Colliders run in the e⁺e^- and e^-e^- modes with both beams longitudinally polarized. We evaluate the model-independent constraints on the contact interaction coupling constants, emphasizing the role of the available beam polarization and the complementarity of the two processes in giving the best constraints.
Key words: anomalous gauge couplings, Bhabha and Møller scattering, polarization
