\midheading{$\nu_{e} e^+ \nu_{\mu} \mu^+ $-pair production via WBF, processes 228,2281}
|
|
The {\it weak} process ({\tt nproc=228}) occurs in $O(\alpha^6)$,
|
|
whereas the {\it strong} process occurs ({\tt nproc=2281}) in $O(\alpha^4 \alpha_S^2)$.
|
|
These processes can currently only be calculated at lowest order.
|
|
\begin{eqnarray}
|
|
&228 & f(p_1)+f(p_2) \to W^+(\nu_e(p_3),e^+(p_4)))W^+(\nu_\mu(p_5),\mu^+(p_6))+f(p_7)+f(p_8) [WBF] \nonumber \\
|
|
&2281 & f(p_1)+f(p_2) \to W^+(\nu_e(p_3),e^+(p_4)))W^+(\nu_\mu(p_5),\mu^+(p_6))+f(p_7)+f(p_8) [strong] \nonumber
|
|
\end{eqnarray}
