Abstract
We investigate the discovery potential for first generation leptoquark s at the LEP200 e(+)e(-) collider. We consider direct leptoquark searc hes using single leptoquark production via resolved photon contributio ns which offers a much higher kinematic limit than the more commonly c onsidered leptoquark pair production process. Depending on the couplin g strength of the leptoquark, search limits can be obtained to within a few GeV of root s. We also consider LQ limits that can be obtained f rom t-channel interferences effects in e(+)e(-) --> hadrons.
