非对易时空上的暴胀

Inflation on a Non-Commutative Space-Time

Xavier Calmet, Christopher Fritz

摘要:

我们在包络代数方法的框架内研究了非对易时空中的暴胀现象,这种方法使得广义相对论和粒子物理学的标准模型具有一致性。我们表明,在这个框架内,时空的非对易性的影响是非常微妙的。主导作用来自于对结构形成过程的贡献。我们描述了这类非交换理论的相关约束,并在此框架内推导出迄今为止最严格的非交换尺度的值。假设暴胀发生,我们得到一个模型无关的约束的时空非交换性的数量级为19 TeV。

英文摘要:

We study inflation on a non-commutative space-time within the framework of enveloping algebra approach which allows for a consistent formulation of general relativity and of the standard model of particle physics. We show that within this framework, the effects of the non-commutativity of spacetime are very subtle. The dominant effect comes from contributions to the process of structure formation. We describe the bound relevant to this class of non-commutative theories and derive the tightest bound to date of the value of the non-commutative scale within this framework. Assuming that inflation took place, we get a model independent bound on the scale of space-time non-commutativity of the order of 19 TeV.
