我们考虑IIB型矩阵模型的相交膜解。结果表明，费米零模出现在这样的背景下，本地化的膜交叉点。在一定条件下，它们导致四维手性费米子。这样的结构再现了类似弦论结构中许多受欢迎的特征。因此，它们可以用来构建半真实的粒子物理模型的框架下的杨米尔斯矩阵模型。特别是，我们提出了一种膜构型，它在矩阵模型中实现了标准模型的正确手征谱。进一步，通过分析1-圈有效作用量，讨论了相交膜的稳定性。它表明，相交膜可以形成一个特定的通量配置的束缚态。膜的四维几何是通用的，并且由矩阵模型的（突现的）引力扇区决定。
We consider intersecting brane solutions of the type IIB matrix model. It is shown that fermionic zero-modes arise on such backgrounds, localized at the brane intersections. They lead to chiral fermions in four dimensions under certain conditions. Such configurations reproduce many of the welcome features in similar string-theoretic constructions. Therefore they can be used to construct semi-realistic particle physics models in the framework of Yang-Mills matrix models. In particular, we present a brane configuration which realizes the correct chiral spectrum of the standard model in the matrix model. Furthermore, the stability of intersecting branes is discussed by analyzing the 1-loop effective action. It is shown that intersecting branes may form a bound state for certain flux configurations. The four-dimensional geometry of the branes is generic, and determined by the (emergent) gravity sector of the matrix model.
