贝叶斯统计的量化自然度
Quantified naturalness from Bayesian statistics
摘要:
我们提出了一个公式的自然贝叶斯统计的框架,它揭开了以前的方法相关的概念问题。除此之外,自然性度量的相对解释被证明是由杰弗里斯的尺度明确建立的。此外,通常的灵敏度公式(所谓的Barbieri-Giudice措施)似乎是嵌入在我们的配方下的扩展形式。我们推导出适用于任意数量的观测量的一般灵敏度公式。进一步讨论了几个后果和发展。作为最后的说明,我们给出了经典超对称模型中与规范层次问题和中性伴子暗物质相关的组合微调映射。
英文摘要:
We present a formulation of naturalness made in the framework of Bayesian statistics, which unravels the conceptual problems related to previous approaches. Among other things, the relative interpretation of the measure of naturalness turns out to be unambiguously established by Jeffreys' scale. Also, the usual sensitivity formulation (so-called Barbieri-Giudice measure) appears to be embedded in our formulation under an extended form. We derive the general sensitivity formula applicable to an arbitrary number of observables. Several consequences and developments are further discussed. As a final illustration, we work out the map of combined fine-tuning associated to the gauge hierarchy problem and neutralino dark matter in a classic supersymmetric model.
