Description

With Higgs boson couplings to vector bosons and heavy fermions being increasingly well-measured at the LHC, the SM Higgs potential is explored further than ever. Yet, the Higgs trilinear self-coupling is still largely unconstrained due to the small cross-section for Higgs boson pair production. I present NLO QCD corrections to Higgs pair production with the full top-quark mass dependence implemented within a non-linear EFT given by the Electroweak Chiral Lagrangian. The fixed-order calculation can be matched to a parton shower program (Herwig7 or Pythia8) in the POWHEG-BOX-V2 MC event generator.
