Enhanced di-Higgs boson production in the complex Higgs singlet model
Enhanced di-Higgs boson production in the complex Higgs singlet model
We consider the Standard Model extended by the addition of a complex scalar singlet, with no assumptions about additional symmetries of the potential. This model provides for resonant di-Higgs production of Higgs particles with different masses. We demonstrate that regions of parameter space allowed by precision electroweak measurements, experimental limits …
