论文摘要
我们认为，以下三个陈述并不是全部。由于几乎所有已知的全球一致的F理论模型都具有标准模型的精确手性谱和量规耦合统一，以中等$ h^{1,1} $出现，因此此发现要求新的模量稳定场景或//和一个丰富的七个武器黑暗领域。
We argue that the following three statements cannot all be true: (i) our vacuum is a type IIB / F-theory vacuum at moderate-to-large $h^{1,1}$, (ii) the $α'$-expansion is controlled via the supergravity approximation, à la the KKLT and LVS scenarios, and (iii) there are no additional gauged sectors from seven-branes. Since nearly all known globally consistent F-theory models with the exact chiral spectrum of the Standard Model and gauge coupling unification occur at moderate $h^{1,1}$, this finding calls for new moduli stabilization scenarios or/and a rich seven-brane dark sector.
