Search for new physics effects in Bhabha scattering at e+e- linear colliders

Abstract

We study electron-electron contact-interaction searches in the process e+ + e- --> e+ + e- at a future linear collider with longitudinally polarized beams, and evaluate the model-independent constraints on the contact interaction parameters, emphasizing the role of beam polarization.
