论文摘要
我们已经构造了来自相交D6烧烤的所有三户元$ {\ cal n} = 1 $ supersymmetrictric pati-salam模型，并总共获得了33个独立模型。但是，如何在这些模型中实现弦尺度量规耦合关系是一个巨大的挑战。我们首先讨论如何将这些模型中的外来颗粒解矛。此外，我们考虑了$ su（4）_c $和$ su（2）_l $ g量符号的伴随性手性mulitplets，d6-brane交叉口的标准模型（SM）矢量样粒子，以及来自$ {\ cal n} = 2 $ sectory的矢量样粒子。我们表明，可以通过为所有这些超对称PATI-SALAM模型运行的两环重新归一化组方程来实现按弦量表的量规耦合关系。因此，我们提出了一种获得通用相交D-Brane模型的字符串尺度量规耦合房地产的具体方法。
We have constructed all the three-family ${\cal N} = 1$ supersymmetric Pati-Salam models from intersecting D6-branes, and obtained 33 independent models in total. But how to realize the string-scale gauge coupling relations in these models is a big challenge. We first discuss how to decouple the exotic particles in these models. In addition, we consider the adjoint chiral mulitplets for $SU(4)_C$ and $SU(2)_L$ gauge symmetries, the Standard Model (SM) vector-like particles from D6-brane intersections, as well as the vector-like particles from the ${\cal N}=2$ subsector. We show that the gauge coupling relations at string scale can be achieved via two-loop renormalization group equation running for all these supersymmetric Pati-Salam models. Therefore, we propose a concrete way to obtain the string-scale gauge coupling realtions for the generic intersecting D-brane models.
