Vector Leptoquark Pair Production in $e^{+}{e}^{-}$ Annihilation

Abstract

The cross section for vector leptoquark pair production in $e^{+}{e}^{-}$ annihilation is calculated for the case of finite anomalous gauge boson couplings ${\kappa }_{\gamma ,Z}$ and ${\lambda }_{\gamma ,Z}$. The minimal cross section is found to behave $\propto {\beta }^7$, leading to weaker mass bounds in the threshold range than in models studied previously.
