高能物理理论中的基本常数及其变率
Fundamental constants and their variability in theories of High Energy Physics
摘要：
粒子物理学的标准模型和广义相对论（GR）目前提供了一个很好的描述几乎所有的粒子物理学和引力现象，已收到控制的实验测试。然而，标准模型包含许多先验变量参数，其值及其表观（接近）恒定性尚未得到令人信服的理论解释。与此同时，GR现在可能需要在最大的长度尺度上进行扩展或改变，以解释最近明显的加速宇宙膨胀。在这篇介绍性的评论中，我提出了寻找基本“常数”的值和可能的变化的解释的理论方面，重点是相互作用的统一的可能性。我也把宇宙学的变化与局部和宇宙学的引力修正联系起来。
英文摘要：
The Standard Model of particle physics and the theory of General Relativity (GR) currently provide a good description of almost all phenomena of particle physics and gravitation that have received controlled experimental tests. However, the Standard Model contains many a priori variable parameters whose values, and whose apparent (near-)constancy, have yet to receive a convincing theoretical explanation. At the same time, GR may now require to be extended or altered at the largest length scales, to account for the recent apparent accelerated cosmological expansion. In this introductory review I present theoretical aspects of the search for explanations of the values and possible variations of fundamental ``constants'', focusing on the possibility of unification of interactions. I also relate cosmological variations to modifications of gravity both locally and cosmologically.
