Abstract
The possibilities to pair-produce leptoquarks in photon-photon collisions a re discussed. QCD threshold corrections lead to a strong enhancement of the production cross-section. Suitably long-lived leptoquarks (Gamma (phi) les s than or similar to 100 MeV) may form Leptoquarkonium states. (C) 2001 Els evier Science B.V. All rights reserved.
