摘要：The search for signals of new physics at the forthcoming LHC experiments involves the analysis
of nal states characterised by a high number of hadronic jets or identied particles. Precise theoretical
predictions for these processes require the computation of scattering amplitudes with a
large number of external particles and beyond leading order in perturbation theory. The complexity
of a calculation grows with the number of internal loops as well as with the number of external
legs. Automatisation of at least next-to-leading order calculations for LHC processes is therefore
a timely task. I will discuss various approaches.
