Leading two-loop corrections to the Higgs boson self-couplings in models with extended scalar sectors
Abstract We compute the dominant two-loop corrections to the Higgs trilinear coupling $$\lambda _{hhh}$$ λhhh and to the Higgs quartic coupling $$\lambda _{hhhh}$$ λhhhh in models with extended Higgs sectors, using the effective-potential approximation. We provide in this paper all necessary details...
