等级- $r$ $\mathcal{N}=2$ SCFT的分类。第一部分:扭曲配分函数和中心荷公式

Towards the classification of rank-$r$ $\mathcal{N}=2$ SCFTs. Part I: twisted partition function and central charge formulae

Mario Martone

摘要:

从库仑分支的相关量出发,直接导出了四维$\mathcal{N}=2$超共形场论(SCFT)的$a$和$c$中心荷的计算公式.这些公式适用于任意等级。我们还发现了$\mathcal{N}=2$ SCFT的风味对称性的低能极限行为的一般性质,最终与我们的$\mathcal{N}=2$ UV-IR简单的风味条件。这是通过精确地确定4d $\mathcal{N}=2$ SCFT的拓扑扭曲版本的配分函数的被积函数与其库仑分支的奇异轨迹之间的关系来完成的。这里开发的技术被广泛应用于许多秩2 SCFT,包括新的,在配套文件。

英文摘要:

We derive explicit formulae to compute the $a$ and $c$ central charges of four dimensional $\mathcal{N}=2$ superconformal field theories (SCFTs) directly from Coulomb branch related quantities. The formulae apply at arbitrary rank. We also discover general properties of the low-energy limit behavior of the flavor symmetry of $\mathcal{N}=2$ SCFTs which culminate with our $\mathcal{N}=2$ UV-IR simple flavor condition. This is done by determining precisely the relation between the integrand of the partition function of the topologically twisted version of the 4d $\mathcal{N}=2$ SCFTs and the singular locus of their Coulomb branches. The techniques developed here are extensively applied to many rank-2 SCFTs, including new ones, in a companion paper.
