为什么我们会观察到弱力?多重宇宙中的等级问题

Why do we observe a weak force? The hierarchy problem in the multiverse

Oram Gedalia, Alejandro Jenkins, Gilad Perez

摘要:

除非电弱对称性破缺的尺度是动态稳定的,否则多元宇宙理论中的大多数宇宙将缺乏可观测到的弱核相互作用。这种“无弱宇宙”可以支持基于有机化学的智能生命,只要其他参数得到适当调整。通过考虑到解决夸克质量和混合层次的完全无关的味道动力学,我们表明,这种弱(但好客)的宇宙可能比我们这样的宇宙更常见。因此,规范层次问题需要一个动力学(而不是人择)的解决方案。

英文摘要:

Unless the scale of electroweak symmetry breaking is stabilized dynamically, most of the universes in a multiverse theory will lack an observable weak nuclear interaction. Such "weakless universes" could support intelligent life based on organic chemistry, as long as other parameters are properly adjusted. By taking into account the seemingly-unrelated flavor dynamics that address the hierarchy of quark masses and mixings, we show that such weakless (but hospitable) universes can be far more common than universes like ours. The gauge hierarchy problem therefore calls for a dynamical (rather than anthropic) solution.
