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.

在具有经典尺度不变的希格斯扇区的电子对称性破坏机制中，希格斯机制从量子校正到有效电位（即Coleman-Weinberg机制）。在这种方法中，实验观察到的125个GEV Higgs质量可以通过大型Higgs自耦合解决方案来容纳在这些规模不变的模型中，而Higgs Boson的较小质量尺度归因于保管经典的量表 - 量表 - 量表 - 量表对称性。随着HIGGS门户相互作用的包含，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一种自然场景。
