LHC phenomenology at next-to-leading order QCD: theoretical progress and new results

Understand

In this talk I report on recent developments and results relevant for LHC phenomenology at next-to-leading order QCD.

• Feynman diagrammatic and unitarity based methods have both seen considerable improvements and new ideas recently.
• Current approaches point towards automated evaluation of one-loop multi-particle amplitudes.
• Many results for notoriously difficult processes are under construction by several groups and, given the enormous recent progress, it can be concluded that LHC phenomenology at full next-to-leading order level will become the standard approximation soon.
