积-群统一是统一理论的一个模型，其中两个希格斯二重态的无质量和无五维质子衰变由一个对称性来保证。它基于SU(5)x U(N)(N=2，3)规范群。众所周知，当模型嵌入到膜世界中时，模型的各种特征被自然地解释。本文描述了如何在IIB型薄膜世界中容纳模型的所有粒子的想法。破肠区由D3-D7系统实现，手征夸克和轻子产生于D7-膜的交点。D膜组态可以是夸克和轻子族非平行族结构的几何实现，这一想法被用来解释在中微子振荡中观察到的大混合角。在某些情况下，次极小超对称标准模型的三线性相互作用是自然得到的。
The product-group unification is a model of unified theories, in which masslessness of the two Higgs doublets and absence of dimension-five proton decay are guaranteed by a symmetry. It is based on SU(5) x U(N) (N=2,3) gauge group. It is known that various features of the model are explained naturally, when it is embedded in a brane world. This article describes an idea of how to accommodate all the particles of the model in Type IIB brane world. The GUT-breaking sector is realized by a D3--D7 system, and chiral quarks and leptons arise from intersection of D7-branes. The D-brane configuration can be a geometric realization of the non-parallel family structure of quarks and leptons, an idea proposed to explain the large mixing angles observed in the neutrino oscillation. The tri-linear interaction of the next-to-minimal supersymmetric standard model is obtained naturally in some cases.
