带3、4电荷物质的阿贝尔F理论模型

Abelian F-theory Models with Charge-3 and Charge-4 Matter

Nikhil Raghuram

摘要:

本文分析了含电荷物质$q=3$和$4$的U(1)F理论模型。首先,我们系统地推导出一个$q=3$的建设,概括了以前的$q=3$的例子。我们认为U(1)对称性可以通过一个类似于SU(N)和Sp(N)调谐过程的过程来调谐。对于具有$q=3$物质的模型,生成部分的分量在电荷3物质轨迹处消失到高于1的阶。因此,Weierstrass模型可以包含非UFD结构,从而偏离标准的Morrison-Park形式。在奇异因子上调整SU(N)模型的技术使我们能够确定非UFD结构,并从头开始推导$q=3$调整。通过变形一个U(1)$\times$ U(1)构造,得到了一类$q=4$模型.据作者所知,这是第一个出版的F理论的例子与电荷-4的问题。最后,我们讨论了电荷大于4的模型的一些性质。

英文摘要:

This paper analyzes U(1) F-theory models admitting matter with charges $q=3$ and $4$. First, we systematically derive a $q=3$ construction that generalizes the previous $q=3$ examples. We argue that U(1) symmetries can be tuned through a procedure reminiscent of the SU(N) and Sp(N) tuning process. For models with $q=3$ matter, the components of the generating section vanish to orders higher than 1 at the charge-3 matter loci. As a result, the Weierstrass models can contain non-UFD structure and thereby deviate from the standard Morrison-Park form. Techniques used to tune SU(N) models on singular divisors allow us to determine the non-UFD structures and derive the $q=3$ tuning from scratch. We also obtain a class of a $q=4$ models by deforming a prior U(1)$\times$U(1) construction. To the author's knowledge, this is the first published F-theory example with charge-4 matter. Finally, we discuss some conjectures regarding models with charges larger than 4.
