等效原理与自然常数

The Equivalence Principle and the Constants of Nature

Thibault Damour

摘要:

我们简要地回顾了各种情况下,其中一个可能解决的问题“为什么”的无量纲常数的性质有特定的价值,他们被观察到。物理学中用动力学实体取代先验给定的绝对结构的一般历史趋势,以及人择的考虑,都表明耦合“常数”具有动力学性质。这暗示了在某种程度上存在可观察到的违反等效原则的情况,并激发了改进等效原则测试的必要性。

英文摘要:

We briefly review the various contexts within which one might address the issue of ``why'' the dimensionless constants of Nature have the particular values that they are observed to have. Both the general historical trend, in physics, of replacing a-priori-given, absolute structures by dynamical entities, and anthropic considerations, suggest that coupling ``constants'' have a dynamical nature. This hints at the existence of observable violations of the Equivalence Principle at some level, and motivates the need for improved tests of the Equivalence Principle.
