论文摘要
我们在4D F理论模型中使用垂直和余数通量对量规对称性进行了一般描述。磁通量可以将几何量规组分解为较小的群体并诱发手性质，即使较大的组不承认手性物质表示。我们专门针对通过破坏刚性杰出量规组$ e_7，e_6 $的标准模型量规组和手性质频谱的应用程序的应用，这在4D F理论景观中是无处不在的。这些大型模型由中间$ \ mathrm {su}（5）$组补充，提供了类似标准模型的理论的自然构造，其中f theory中的物质几代。
We give a general description of gauge symmetry breaking using vertical and remainder fluxes in 4D F-theory models. The fluxes can break a geometric gauge group to a smaller group and induce chiral matter, even when the larger group admits no chiral matter representations. We focus specifically on applications to realizations of the Standard Model gauge group and chiral matter spectrum through breaking of rigid exceptional gauge groups $E_7, E_6$, which are ubiquitous in the 4D F-theory landscape. Supplemented by an intermediate $\mathrm{SU}(5)$ group, these large classes of models give natural constructions of Standard Model-like theories with small numbers of generations of matter in F-theory.
