Abstract
A bstract We present the implementation of Higgs boson pair production in gluon fusion within a non-linear Effective Field Theory framework containing five anomalous couplings for this process. The code, available within the POWHEG-BOX-V2, includes full NLO QCD corrections with massive top quarks. All five couplings can be modified by the user. We show m hh distributions at seven benchmark points provided by an m hh shape analysis at NLO and showered $$ {p}_T^{hh} $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mi>p</mml:mi> <mml:mi>T</mml:mi> <mml:mi>hh</mml:mi> </mml:msubsup> </mml:math> distributions resulting from an interface to PYTHIA-8 and HERWIG-7.2.
