Description
Precision HH predictions: QCD and EW corrections
In this talk I will discuss some recent work on the use of expansions in various kinematic limits to make sense of complicated multi-scale multi-loop amplitudes. In particular, I will discuss how expansions in the high-energy and small-t limits can provide a good approximation of the virtual amplitude for di-Higgs production in gluon fusion. I will discuss two-loop amplitudes for both QCD and EW corrections, and some early work on three-loop QCD corrections.
