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

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

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 fo...
