局部方面的奇异F-理论紧化的超对称大统一模型的建设是相当好的理解,在希格斯束和他们的光谱数据。然而,仍有几个全球性的问题,包括G通量的描述,这是构建手征物质和稳定模的关键,以及U(1)对称性的全球实现,可以禁止现象学上不利的耦合。在本文中,我们加强了我们以前的建议,描述G-通量通过“谱因子”,并引入了一个独特的“泰特因子”,它可以用来描述G-通量和U(1)的时候。作为一个应用程序,我们给出了一个一般性的讨论M5-瞬子的贡献在G-通量的存在下,并在一个具体的例子中,我们评论瞬子引起的超势耦合稳定Kahler模量的能力。
Local aspects of singular F-theory compactifications for SUSY GUT model-building are fairly well understood in terms of Higgs bundles and their spectral data. Several global issues remain, however, including a description of G-fluxes, which are key to constructing chiral matter and stabilizing moduli, and the global realization of U(1) symmetries that can forbid phenomenologically unfavorable couplings. In this paper, we sharpen our earlier proposal for describing G-fluxes through "spectral divisors" and introduce a distinguished "Tate divisor", which can be used to describe both G-flux and U(1)s when present. As an application, we give a general discussion of M5-instanton contributions in the presence of G-flux and exemplify this in a concrete example, where we comment on the ability of instanton induced superpotential couplings to stabilize Kahler moduli.
