粒子物理学的标准模型存在于大量的弦真空中。在弦理论的非摄动表述中，原则上可以动态地比较各种弦真空，并计算真空空间上的概率分布。在本文中，我们考虑了IIB矩阵模型在具有各种规群和各种磁通的六维环面上紧化的情况，找到了提供标准模型物质含量的矩阵构型，并估计了它们出现的半经典概率。
The standard model of particle physics lies in an enormous number of string vacua. In a nonperturbative formulation of string theory, various string vacua can, in principle, be compared dynamically, and the probability distribution over the vacuum space could be calculated. In this paper, we consider situations where the IIB matrix model is compactified on a six-dimensional torus with various gauge groups and various magnetic fluxes, find matrix configurations that provide the standard model matter content, and estimate semiclassically the probability of their appearance.
