Title:     Resonant Di-Higgs Production in the Higgs Singlet Model

Abstract: Higgs pair production at the LHC from gluon fusion is small in the Standard Model, but can be enhanced in models where a resonant enhancement is allowed.  We study the enhancement of the di-Higgs production cross section resulting from the decay of a heavy Higgs boson at hadron colliders in a model with a Higgs singlet. This enhancement of the double Higgs production rate is crucial in understanding the structure of the scalar potential and we determine the maximum allowed enhancement such that the electroweak minimum is a global minimum.  We also compute the NLO QCD corrections in the large mt limit and show that they can be significant.​

Special time!
