Anomalous couplings in Higgs-boson pair production at approximate NNLO QCD

Abstract

Abstract We combine NLO predictions with full top-quark mass dependence with approximate NNLO predictions for Higgs-boson pair production in gluon fusion, including the possibility to vary coupling parameters within a non-linear Effective Field Theory framework containing five anomalous couplings for this process. We study the impact of the anomalous couplings on various observables, and present Higgs-pair invariant-mass distributions at seven benchmark points characterising different m hh shape types. We also provide numerical coefficients for the approximate NNLO cross section as a function of the anomalous couplings at s $$ \sqrt{s} $$ = 14 TeV.
