一个残基统治一切:电弱对称性破缺,暴胀和场空间几何

One residue to rule them all: Electroweak symmetry breaking, inflation and field-space geometry

Georgios K. Karananas, Marco Michel, Javier Rubio

摘要:

我们指出,在某些标量-张量理论中,通过引力瞬子组态成功产生的电弱标度可以被看作是一个简单要求的后果:在爱因斯坦框架动力学项中存在一个足够小的剩余的希格斯场的二次极点。在某些情况下,暴胀动力学也可能由这个剩余控制,因此与费米-普朗克质量比有关,直到与瞬子正则化相关的可能的不确定性。我们在这里提出了一个统一的框架,这个层次的生成机制,表明上述残留物可以与爱因斯坦框架的目标流形的曲率模型显示自发破缺。我们的研究结果说明,通过以前在文献中考虑的例子。

英文摘要:

We point out that the successful generation of the electroweak scale via gravitational instanton configurations in certain scalar-tensor theories can be viewed as the aftermath of a simple requirement: the existence of a quadratic pole with a sufficiently small residue in the Einstein-frame kinetic term for the Higgs field. In some cases, the inflationary dynamics may also be controlled by this residue and therefore related to the Fermi-to-Planck mass ratio, up to possible uncertainties associated with the instanton regularization. We present here a unified framework for this hierarchy generation mechanism, showing that the aforementioned residue can be associated with the curvature of the Einstein-frame target manifold in models displaying spontaneous breaking of dilatations. Our findings are illustrated through examples previously considered in the literature.
