Calculating multileg one-loop processes. The case of gg -> t bar_t+gg
arXiv:1005.5256 · doi:10.1016/j.nuclphysbps.2010.08.024
Abstract
This study is targeted to the NLO corrections of multileg processes, very important for the LHC. Starting from the construction of Feynman diagrams, the analytical reduction of general one-loop integrals to scalar master ones, the calculation of color structures, manipulation of spinor lines and other amplitude constituents and finally phase space point selection are obtained by use of a program producing Fortran code for numerical calculation of one-loop corrections for processes like gg -> t bar_t+gg.
