Resolved photon contributions to leptoquark production in e+e- and eγ collisions

We calculate the resolved photon contribution to leptoquark production at e γ colliders for the center-of-mass energies √ s = 500 GeV and 1 TeV. We also calculate the resolved photon contribution to leptoquark production at e + e − colliders for the center of mass energies √ s = 1 and 2 TeV. In both cases we find that these contributions are considerably larger than the standard contributions considered in the literature. In addition we find that polarized electron beams would be able to determine the chirality of the leptoquarks and therefore be crucial for the determination of the type of leptoquark discovered
