AI总结:

本文提出通过共形不变标量扇区的非微扰动力学产生电弱尺度,并利用Dyson-Schwinger方法在强耦合区域解析计算希格斯质量,同时论证希格斯扇区对规范理论获得质量不可或缺,为规范等级问题及一般尺度生成提供新思路。

摘要:

我们提出了一条新途径,通过在经典层面上具有共形不变性的标量扇区的非微扰动力学来产生电弱(EW)尺度。我们提供了一种方法,利用Dyson-Schwinger方法中标量理论背景运动方程的精确解来估计非微扰电弱尺度的产生。特别地,我们在强耦合区域中找到了希格斯质量的解析结果,该结果以其四次自相互作用项和理论的截断尺度表示。我们还表明,希格斯扇区是标准模型的一个基本组成部分,因为没有它,即使存在自相互作用项,Yang-Mills规范理论也无法获得质量。我们的分析导向更现实的模型构建,可能解决规范等级问题,并且一般来说,导向自然界中任何尺度的动力学产生,无论是可见扇区还是暗扇区。

英文摘要:

We propose a novel pathway to generate the electroweak (EW) scale via non-perturbative dynamics of a conformally invariant scalar sector at the classical level. We provide a method to estimate the non-perturbative EW scale generation using the exact solution of the background equations of motion in a scalar theory via the Dyson-Schwinger approach. Particularly, we find an analytical result for the Higgs mass in the strongly coupled regime in terms of its quartic self interaction term and the cut-off scale of the theory. We also show that the Higgs sector is an essential part of the Standard Model as, without it, a Yang--Mills gauge theory cannot acquire mass even if a self-interaction term is present. Our analysis lead to a more realistic model building with possible solutions to the gauge hierarchy problem and, in general, to the dynamical generation of any scales scales in nature, be it the visible sector or the dark sector.
