摘要:

我们构造了具有三个手征代的四维全局一致F理论模型,其规范群和物质表示与最小超对称标准模型、Pati-Salam模型和三位一体化模型的规范群和物质表示一致.这些模型的结果从环面纤维$X$与基地$\mathbb{P}^3$的选择紧化。我们观察到的F-理论条件的$G_4$ -通量限制的家庭的数量至少为3。我们评论的唯象模型,并为Pati-Salam和Trinification模型讨论了希格斯到标准模型。这项工作的一个中心点是全球一致的$G_4$ -通量的建设。为此目的,我们计算的垂直上同调$H_V^{(2,2)}(X)$在每种情况下,并解决由匹配的M-和F-理论的3D陈-西蒙斯条款所施加的条件。我们明确地检查,发现的表达式为$G_4$通量允许取消D3膜蝌蚪。我们还使用3D Chern-Simons条款的完整性,以确保我们的$G_4$通量的解决方案是充分量化的。

英文摘要:

We construct four-dimensional, globally consistent F-theory models with three chiral generations, whose gauge group and matter representations coincide with those of the Minimal Supersymmetric Standard Model, the Pati-Salam Model and the Trinification Model. These models result from compactification on toric hypersurface fibrations $X$ with the choice of base $\mathbb{P}^3$. We observe that the F-theory conditions on the $G_4$-flux restrict the number of families to be at least three. We comment on the phenomenology of the models, and for Pati-Salam and Trinification models discuss the Higgsing to the Standard Model. A central point of this work is the construction of globally consistent $G_4$-flux. For this purpose we compute the vertical cohomology $H_V^{(2,2)}(X)$ in each case and solve the conditions imposed by matching the M- and F-theoretical 3D Chern-Simons terms. We explicitly check that the expressions found for the $G_4$-flux allow for a cancelation of D3-brane tadpoles. We also use the integrality of 3D Chern-Simons terms to ensure that our $G_4$-flux solutions are adequately quantized.
