自然规范玻色子质量的计算方法

A technique for natural gauge boson masses

Benjamin Koch, Cristobal Laporte

摘要:

本文提出了一种新的自发对称性破缺机制。这种机制避免了二次发散,因此能够解决规范理论中的层次问题。使用尺度相关的有效作用量$Γ_{k}$最小耦合到一个引力扇区,变分参数设置应用。这提供了一个质量和真空期望值,作为牛顿和宇宙学耦合的低尺度膨胀中产生的常数的函数。与实验数据(如希格斯质量)的比较允许对这些常数进行限制。用这种通用的方法,人们可以与引力的有效场论的明确候选者进行比较。作为一个例子,我们使用的渐近安全的情况下,我们发现限制的理论内容。

英文摘要:

In this work, a novel mechanism for spontaneous symmetry breaking is presented. This mechanism avoids quadratic divergencies and is thus capable of addressing the hierarchy problem in gauge theories. Using the scale-dependent effective action $Γ_{k}$ minimally coupled to a gravitational sector, variational parameter setting is applied. This provides a mass and vacuum expectation value as a function of the constants arising in the low scale expansion of Newtons' and cosmological couplings. A comparison with experimental data, such as the Higgs mass, allows putting restrictions on these constants. With this generic approach one can compare with explicit candidates for an effective field theory of gravity. As an example, we use the asymptotic safety scenario, where we find restrictions on the matter content of the theory.
