最小速度不变的变形狭义相对论及其宇宙学意义

Deformed special relativity with an invariant minimum speed and its cosmological implications

Claudio Nassif

摘要:

本文的目的是通过消除经典的静止思想,并通过在亚原子世界中引入一个普遍的最小速度极限,在时空几何中引入一个新的对称性原理。这样一个粒子无法达到的极限,代表了一个与破坏洛伦兹对称性的普遍背景场相关联的优选参考系。因此,时空的结构由于真空能量密度的存在而扩展,这导致了宇宙尺度上的负压。成功地获得了宇宙学常数和真空能量密度的微小值,并与目前的观测结果相符合。

英文摘要:

The paper aims to introduce a new symmetry principle in the space-time geometry through the elimination of the classical idea of rest and by including a universal minimum limit of speed in the subatomic world. Such a limit, unattainable by particles, represents a preferred reference frame associated with a universal background field that breaks Lorentz symmetry. Thus the structure of space-time is extended due to the presence of a vacuum energy density, which leads to a negative pressure at cosmological scales. The tiny values of the cosmological constant and the vacuum energy density shall be successfully obtained, being in good agreement with current observational results.
