Composite vector leptoquarks ine+e−,γe, andγγcolliders

Abstract

We study the signals for composite vector leptoquarks in $e^{+}{e}^{-}$ colliders (CERN $e^{+}{e}^{-}$ collider, LEP II, Next Linear Collider, and CERN Linear Collider) through their effects on the production of jet pairs, as well as their single and pair productions. We also analyze their production in $\gamma e$ and $\gamma \gamma$ collisions.
