Leptoquark Pair Production in \gamma\gamma Scattering: Threshold Resummation

The possibilities to pair-produce leptoquarks in photon-photon collisions are discussed. QCD threshold corrections lead to a strong enhancement of the production cross section. Suitably long-lived leptoquarks (\Gamma_\Phi \lsim 100 \MeV) may form Leptoquarkonium states.Comment: 7 pages LATEX, 2 eps figures. Contribution to the Proceedings of the \gamma \gamma Workshop, 200
