Single vector leptoquark production at gammae and gammap colliders

We study single vector leptoquark production at future e and p colliders. The production cross sections are calculated for both e and p 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.
