Main/0-174 - Auditorium (Main)

In the first part of the talk, precision calculations will be motivated and briefly reviewed, in particular for two-loop amplitudes involving several mass scales.

The second part is dedicated to Higgs boson pair production, focusing on the combination of QCD corrections with anomalous couplings in an Effective Field Theory framework. Predictions for the Higgs boson pair invariant mass spectrum, including leading operators as well as loop-suppressed operators, will be presented and various sources of uncertainties will be discussed.
