摘要:

E6大统一理论是介于标准模型和弦论之间的一个有吸引力的候选中间理论。然而,文献中从弦论中只导出了一个具有三代和至少一个伴随Higgs场的E6大统一模型,而且这个模型在唯象上是不令人满意的。最近,在arXiv:1012.1690中,我们在杂种非对称轨道折叠中构建了两个新的E6大统一模型。虽然我们的新模型本身不能解决以前模型中不令人满意的地方,但我们的发现带来了希望,人们可以在这个框架内构建许多其他这样的模型,并找到更好的模型。在这里,通过明确地给出配分函数,我们解释了我们构造的细节。利用格点工程技术和对角嵌入方法,我们可以系统地构造模型。我们希望,这些技术和我们的建设细节将导致更多的现象学理想的模型。

英文摘要:

The E6 grand unified theory is an attractive candidate intermediate theory between the standard model and string theory. However, only one E6 grand unified model with three generations and at least one adjoint Higgs field has been derived from string theory in the literature, and this model is phenomenologically unsatisfactory. Recently, in arXiv:1012.1690, we have constructed two new such E6 grand unified models in heterotic asymmetric orbifolds. Although our new models themselves cannot resolve the unsatisfactory point in the previous model, our discovery raises hopes that one can construct many other such models in this framework and find better models. Here, by giving partition functions explicitly, we explain the details of our construction. Utilizing the lattice engineering technique and the diagonal embedding method, we can construct models systematically. We hope that these techniques and the details of our construction will lead to more phenomenologically desirable models.
