\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}
