Stueckelberg大质量光子设计的暴胀和晚期加速

Inflation and late time acceleration designed by Stueckelberg massive photon

Ozgur Akarsu, Metin Arik, Nihan Katirci

摘要:

本文在闵可夫斯基和弯曲时空的框架下,对Stueckelberg机制进行了简要的评述,该机制的提出是为了使阿贝尔规范理论成为Higgs机制的替代方案。尺度越高,光子质量的界限就越紧,这可能是通过施图克尔伯格机制获得的,这可能表明即使是无法直接测量的极小质量的光子也可能在宇宙学中产生深远的影响。我们提出了一个宇宙学模型,其中的Stueckelberg场,它包括标量场和矢量场,是非最小耦合到重力和宇宙可以通过一个减速膨胀阶段夹在两个不同的加速膨胀阶段。我们还讨论了可能的各向异性扩展的模型。

英文摘要:

We present a mini review of the Stueckelberg mechanism, which was proposed to make the abelian gauge theories massive as an alternative to Higgs mechanism, within the framework of Minkowski as well as curved spacetimes. The higher the scale the tighter the bounds on the photon mass, which might be gained via the Stueckelberg mechanism, may be signalling that even an extremely small mass of the photon which cannot be measured directly could have far reaching effects in cosmology. We present a cosmological model where Stueckelberg fields, which consist of both scalar and vector fields, are non-minimally coupled to gravity and the universe could go through a decelerating expansion phase sandwiched by two different accelerated expansion phases. We discuss also the possible anisotropic extensions of the model.
