Description

Processes with more than 5 legs are added to experimentalists' wish list for a long time now. This study is targeted to the NLO qcd corrections of such processes in the LHC. Many Feynman diagrams are contributing, including those with five- and six-point functions. A Fortran code for the numerical calculation of one-loop corrections for the process $gg\rightarrow t \bar{t}+gg$ is reviewed. A variety of tools like Diana, Form, Maple, Fortran are used in combination.
