摘要：
We discuss the combination of the NLO QCD matrix element for double Higgs boson production with a parton shower, including the full top-quark mass dependence. Since the 2-loop double Higgs boson production amplitude is currently known only numerically, in order to produce a fast and stable code for the evaluation of the virtual matrix element, we construct a grid based on a fixed number of precomputed phase-space points. Results are generated in both the POWHEG-BOX and MadGraph5_aMC@NLO Monte Carlo frameworks and showered with Pythia. We investigate the sensitivity of showered predictions of the Higgs boson pair transverse momentum distribution to the parameters of the POWHEG matching scheme.
