Vector Leptoquark Pair Production in $e^+e^-$ Annihilation
  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.
