Single vector leptoquark production at γe and γp colliders

We study single vector leptoquark production at future γe and γp colliders. The production cross sections are calculated for both γe and γp collisions. Analytical expressions are derived for the differential cross sections including the case of anomalous vector LQ coupling, a, to the photon. We find that the cross sections for single production of vector LQs have a rather weak dependence on the parameter a. The discovery limits for the masses of vector LQs are obtained for both cases.
