通过6d SCFT分类5d SCFT:Rank 1

Classifying 5d SCFTs via 6d SCFTs: Rank one

Lakshya Bhardwaj, Patrick Jefferson

摘要:

根据最近的一项建议,我们描绘了一个一般的程序来分类5D SCFT通过紧化6D SCFT在一个圆(可能有一个扭曲的离散的全球对称性)。从6d SCFT到5d SCFT的路径可以分为两个步骤。第一步是计算有限半径的圆上的6d SCFT紧化得到的5d KK理论的库仑分支数据。第二步是计算KK理论的极限,当半径的倒数和其他一些质量参数被送到无穷大时。在此RG流下,KK理论简化为5d SCFT。我们说明了这些想法的情况下,无扭曲的紧化秩6D SCFT,可以在F-理论没有冻结奇点。相应的KK理论的数据可以打包成卡-丘三重几何,我们对每种情况都明确计算。RG流对应于在三重中翻转一组曲线,我们制定了一套具体的标准,可用于确定哪些曲线可以诱导相关的RG流,并在原则上,以确定描述这些流的端点的卡-丘几何。我们还评论了如何将我们的结果推广到任意秩。

英文摘要:

Following a recent proposal, we delineate a general procedure to classify 5d SCFTs via compactifications of 6d SCFTs on a circle (possibly with a twist by a discrete global symmetry). The path from 6d SCFTs to 5d SCFTs can be divided into two steps. The first step involves computing the Coulomb branch data of the 5d KK theory obtained by compactifying a 6d SCFT on a circle of finite radius. The second step involves computing the limit of the KK theory when the inverse radius along with some other mass parameters is sent to infinity. Under this RG flow, the KK theory reduces to a 5d SCFT. We illustrate these ideas in the case of untwisted compactifications of rank one 6d SCFTs that can be constructed in F-theory without frozen singularities. The data of the corresponding KK theory can be packaged in the geometry of a Calabi-Yau threefold that we explicitly compute for every case. The RG flows correspond to flopping a collection of curves in the threefold and we formulate a concrete set of criteria which can be used to determine which collection of curves can induce the relevant RG flows, and, in principle, to determine the Calabi-Yau geometries describing the endpoints of these flows. We also comment on how to generalize our results to arbitrary rank.
