论文摘要
我们构建了一个4D n = 2个SCFT的一组示例，其分级的库仑分支尺寸，weyl-Anomaly系数和风味对称代数及其水平重合，但仍然是不同的SCFT。差异（可通过超符号索引可检测）可以在任意高阶中发生。我们认为，它反映在风味对称群的全球形式的差异中。
We construct a family of examples of pairs of 4d N=2 SCFTs whose graded Coulomb branch dimensions, Weyl-anomaly coefficients and flavour symmetry algebras and levels coincide, but which are nonetheless distinct SCFTs. The difference (detectable by the superconformal index) can occur at arbitrarily high order. We argue that it is, however, reflected in a difference in the global form of the flavour symmetry groups.
