论文摘要
大量（亚稳态的）真空解决方案来自弦弦压缩，每种都会导致物理4-D定律。这些解决方案的空间（称为弦景观）可以解决宇宙恒定问题的环境解决方案。我们研究了仪表层次结构问题的环境解决方案的可能性。我们认为，景观偏爱柔软破碎的超对称模型，而不是包含二次差异的粒子物理模型，例如标准模型。我们提出了一种计算相对概率的方案，以使超对称模型从景观中出现。概率与弱尺度的派生值位于Agrawal等人内的可能性有关。 （ABDS）允许众所周知的值窗口通向原子。然后，通过可计算的概率度量，这比自然模型（SUSY和其他）模型有利于自然模型。
A vast array of (metastable) vacuum solutions arise from string compactifications, each leading to different 4-d laws of physics. The space of these solutions, known as the string landscape, allows for an environmental solution to the cosmological constant problem. We examine the possibility of an environmental solution to the gauge hierarchy problem. We argue that the landscape favors softly broken supersymmetric models over particle physics models containing quadratic divergences, such as the Standard Model. We present a scheme for computing relative probabilities for supersymmetric models to emerge from the landscape. The probabilities are related to the likelihood that the derived value of the weak scale lies within the Agrawal et al. (ABDS) allowed window of values leading to atoms as we know them. This then favors natural SUSY models over unnatural (SUSY and other) models via a computable probability measure.
