核有效场论中的自然性

Naturalness in Nuclear Effective Field Theories

U. van Kolck

摘要:

核有效场论(EFT)在过去的四分之一个世纪里得到了发展,对轻核甚至中等质量核的描述产生了相当大的影响。任何EFT的核心都是对可观察量的系统扩展,这通常是从基于自然性假设的规则中获得的。我讨论的背景下,相对较弱的约束力的核,离散尺度不变性的复杂性的出现中发挥了作用的自然性。

英文摘要:

Nuclear effective field theories (EFTs) have been developed over the last quarter-century with considerable impact on the description of light and even medium-mass nuclei. At the core of any EFT is a systematic expansion of observables, which is usually obtained from a rule based on an assumption of naturalness. I discuss naturalness in the context of the relatively weak binding of nuclei, where discrete scale invariance plays a role in the emergence of complexity.
