论文摘要
我们构建了新的三户$ {\ cal n} = 1 $ supersymmetric pati-salam型号，来自与原始量规组$ {\ rm u}（4）_c \ times {\ rm usp}（\ rm usp}（2）（2）_l \ rm um um um um u}（\ rm u}（2）（2）（2）（2）type类型IAIA， $ \ mathbb {t}^6/（\ mathbb {z} _2 \ times \ times \ mathbb {z} _2）$ orientifold。我们发现，用$ {\ rm usp}（2）$ {\ rm u}（2）$替换为$ ofter的三代超对称模型的数量，只有五个不相等的模型。在交换左侧和右侧的扇区，我们获得了五个具有量规组$ {\ rm u}（4）_c \ times {\ rm u}（2）_l \ times {\ rm usp}（2）_r $的双重模型。这十个模型以弦尺度具有不同的量规耦合关系。最高的包装编号为4，其中一种模型不包含填充O6平板。此外，我们详细讨论了粒子光谱，通过强耦合动力学的复合粒子以及外来粒子的脱钩。另外，我们研究了如何在某些模型中实现弦尺度量规耦合关系。
We construct new three-family ${\cal N}=1$ supersymmetric Pati-Salam models from intersecting D6-branes with original gauge group ${\rm U}(4)_C \times {\rm USp}(2)_L \times {\rm U}(2)_R$ on a Type IIA $\mathbb{T}^6/(\mathbb{Z}_2\times \mathbb{Z}_2)$ orientifold. We find that replacing a ${\rm U}(2)$ with a ${\rm USp}(2)$ group severely restricts the number of three-generation supersymmetric models such that there are only five inequivalent models. Exchanging the left and right sectors, we obtain five dual models with gauge group ${\rm U}(4)_C \times {\rm U}(2)_L \times {\rm USp}(2)_R$. These ten models have different gauge coupling relations at string scale. The highest wrapping number is 4, and one of the models contains no filler O6-planes. Moreover, we discuss in detail the particle spectra, the composite particles through strong coupling dynamics, and the exotic particle decouplings. Also, we study how to realize the string-scale gauge coupling relations in some models.
