粒子物理学的标准模型作为一种阴谋论和希格斯玻色子在早期宇宙演化中的可能作用

The Standard Model of particle physics as a conspiracy theory and the possible role of the Higgs boson in the evolution of the early universe

Fred Jegerlehner

摘要:

我正在考虑Veltman的“红外-紫外线连接”解决二次发散问题和相关的巨大辐射修正预测的电弱标准模型(SM)之间的关系裸和重整化理论,通常称为“层次问题”,这通常是声称,这是必须治愈。在欧洲核子研究中心发现希格斯粒子之后,SM基本上完成了,规范玻色子、顶夸克和希格斯玻色子玻色子的主要相互作用强度之间惊人的相互关系显示,SM允许将运行耦合微扰外推到普朗克尺度。核心问题涉及电弱真空的稳定性,这需要运行的希格斯自耦合保持为正。虽然一些评价似乎有利于亚稳定性的实验和理论参数的不确定性,不应该排除的可能性,其他实验和改进的匹配条件将能够建立绝对稳定的SM真空在未来。我将讨论稳定真空的情况及其对早期宇宙学的影响,揭示作为暴胀子的希格斯玻色子。事实证明,当我们把标准模型理解为从普朗克尺度的截止介质中出现的低能有效尾时,标准模型假定的“层次问题”和类似的“宇宙学常数问题”就解决了。当考虑SM耦合的能量依赖性时,希格斯玻色子质量重整化所传达的“红外-紫外联系”以新的方式出现。裸露的希格斯玻色子质量平方在普朗克尺度下改变符号,激活希格斯机制。

英文摘要:

I am considering Veltman's "The Infrared - Ultraviolet Connection" addressing the issue of quadratic divergences and the related huge radiative correction predicted by the electroweak Standard Model (SM) in the relationship between the bare and the renormalized theory, commonly called "the hierarchy problem" which usually is claimed that this has to be cured. After the discovery of the Higgs particle at CERN, which essentially completed the SM, an amazing interrelation of the leading interaction strengths of the gauge bosons, the top-quark and the Higgs boson showed up amounting that the SM allows for a perturbative extrapolation of the running couplings up to the Planck scale. The central question concerns the stability of the electroweak vacuum, which requires that the running Higgs self-coupling stays positive. Although several evaluations seem to favor the meta-stability within the experimental and theoretical parameter-uncertainties, one should not exclude the possibility that other experiments and improved matching conditions will be able to establish the absolute stability of the SM vacuum in the future. I will discuss the stable vacuum scenario and its impact on early cosmology, revealing the Higgs boson as the inflaton. It turns out that the Standard Model's presumed "hierarchy problem" and similarly the "cosmological constant problem" resolve themselves when we understand the SM as a low energy effective tail that is emergent from a cutoff-medium at the Planck scale. "The Infrared - Ultraviolet Connection" conveyed by the Higgs boson mass renormalization appears in a new light when the energy dependence of the SM couplings is taken into account. The bare Higgs boson mass square then changes sign below the Planck scale where it is activating the Higgs mechanism.
