Higgs boson pair production in non-linear Effective Field Theory with full m t -dependence at NLO QCD

Higgs boson pair production in non-linear Effective Field Theory with full m t -dependence at NLO QCD

Abstract We present a calculation of the NLO QCD corrections to Higgs boson pair production within the framework of a non-linearly realised Effective Field Theory in the Higgs sector, described by the electroweak chiral Lagrangian. We analyse how the NLO corrections affect distributions in the Higgs...
