\midheading{$e^- \bar\nu_{e} \nu_{\mu} \mu^+$-pair production via WBF, processes 224,2241}
|
|
The {\it weak} process ({\tt nproc=224}) occurs in $O(\alpha^6)$,
|
|
whereas the {\it strong} process ({\tt nproc=2241}) occurs in $O(\alpha^4 \alpha_S^2)$.
|
|
These processes can currently only be calculated at lowest order.

|
\begin{eqnarray}
|
|
&224 & f(p_1)+f(p_2) \to W^-(e^-(p_3),\bar{\nu}_e(p_6)))W^+(\nu_\mu(p_5),\mu^+(p_4))+f(p_7)+f(p_8) [WBF] \nonumber

\\

&2241 & f(p_1)+f(p_2) \to W^-(e^-(p_3),\bar{\nu}_e(p_6)))W^+(\nu_\mu(p_5),\mu^+(p_4))+f(p_7)+f(p_8) [strong]
