Automated higher-order calculations: Status and prospects
Abstract
In this presentation we review the current status in the automated evaluation of scattering amplitudes, with particular attention to the developments related with NLO calculations, which led to the construction of powerful multi-purpose computational tools. After a general overview, we will devote a short section to describe the GoSam framework for NLO calculations and its application to the production of Higgs boson plus jets. We will then briefly comment on the challenges presented by NNLO calculations, whose structure is considerably more complicated. Finally, we will describe some of the features of the integrand-reduction techniques beyond NLO, an alternative promising approach to multi-loop calculations which is currently under development.
