Effective Field Theory Wednesday Session B


Jannis Lang


We present results for Higgs boson pair production in gluon fusion
at NLO (2-loop) QCD including operators in the Standard Model Effective Field Theory (SMEFT) framework.
Contributions from subsets of higher order terms in $\frac{1}{\Lambda^2}$,
such as squared dimension-6 operators at cross section level and double operator insertions at amplitude level, are used as a proxy
for the study of truncation effects of the SMEFT expansion. The different truncation options are contrasted
to the non-linear Higgs Effective Field Theory (HEFT) framework for selected phenomenological examples.
