Abstract

We discuss the triviality and spontaneous symmetry breaking scenario where the Higgs boson without self-interaction coexists with spontaneous symmetry breaking. We argue that nonperturbative lattice investigations support this scenario. Moreover, from lattice simulations, we predict that the Higgs boson is rather heavy. We estimate the Higgs boson mass π‘š 𝐻 = 7 5 4 Β± 2 0 (stat) Β± 2 0 (syst) GeV and the Higgs total width Ξ“ ( 𝐻 ) ≃ 3 4 0  GeV.
