\midheading{$\nu_e  e^+ \mu^- \mu^+$-pair production via WBF, processes 223,2231}
The {\it weak} process ({\tt nproc=223})  occurs in $O(\alpha^6)$, 
whereas the {\it strong} process occurs ({\tt nproc=2231}) in $O(\alpha^4 \alpha_S^2)$.  These processes
can currently only be calculated at lowest order.
\begin{eqnarray}
& 223  & f(p_1)+f(p_2) \to W^+(\nu_e(p_3),e^+(p_4))Z(\mu^-(p_5),\mu^+(p_6)))+f(p_7)+f(p_8) [weak]  \nonumber \\
& 2231 & f(p_1)+f(p_2) \to W^+(\nu_e(p_3),e^+(p_4))Z(\mu^-(p_5),\mu^+(p_6)))+f(p_7)+f(p_8) [strong]  \nonumber
\end{eqnarray}
