In electroweak symmetry breaking mechanisms with classically scale-invariant Higgs sectors, the Higgs mechanism emerges from the quantum corrections to the effective potential (i.e. the Coleman-Weinberg mechanism). In this approach, the experimentally observed 125 GeV Higgs mass can be accommodated in these scale-invariant models by a large Higgs self-coupling solution, and the small mass scale of the Higgs boson is attributed to a custodial classical scale-invariance symmetry.  With the inclusion of a Higgs portal interaction, extensions of this mechanism beyond the Standard Model  provides a natural scenario for cosmologically-stable dark matter.

在具有经典尺度的nvariant Higgs扇区的Electroweak对称性中归因于自定义的古典 - 差异对称性，包括Higgs门户相互作用，该机制的扩展超出了标准模型，为宇宙学稳定的暗物质提供了自然的情况。
