Single vector leptoquark production in $gammagamma$ collider

Abstract

We present the single vector Leptoquark (LQ) production in $gammagamma$ collider for two values of the center of mass energy $sqrt{s}$ = 1000 GeV. We performed our calculations for two cases, depending on whether LQ's are gauge vector particles or non-gauge vector particles. We find that the cross sections for thi sengle gauge and non-gauge vector LQ productions are almost equal. The discovery limit for single vector LQ production is obtained for both cases. It is shown that $gammagamma$ beams is more preferable than the $e^+ e^-$ beams for the single second and third generation vector LQ production.
