====== TTP08-31 Automating dipole subtraction ====== We report on automating the Catani-Seymour dipole subtraction which is a general procedure to treat infrared divergences in real emission processes at next-to-leading order in QCD. The automatization rests on three essential steps: the creation of the dipole terms, the calculation of the color linked squared Born matrix elements, and the evaluation of different helicity amplitudes. The routines have been tested for a number of complex processes, such as the real emission process gg --> t anti-t ggg. |**K.Hasegawa, S.Moch, P.Uwer** | |** Nucl.Phys.Proc.Suppl. 183 268-273 2008 ** | | {{preprints:2008:ttp08-31.pdf|PDF}} {{preprints:2008:ttp08-31.ps|PostScript}} [[http://arxiv.org/abs/0807.3701|arXiv]] | | |
