Abstract

Motivated by the demand for a higher accuracy description of the multi-particle processes that will take place at the upcoming LHC experiment, the theoretical efforts to develop new computational techniques for perturbative calculation have received a strong boost, stemmed from on-shell techniques and unitarity-based methods.
