标题： On Twisted $A_{2n}$ Class-S Theories

摘要： 本文中，我们研究了类-S理论的扭曲$A_{2n}$部分。迄今为止，这类理论的库仑分支尚不为人所知。在此以及相关论文中，我们在理解它们方面取得了进展。特别是，我们找到了任意扭曲$A_{2n}$类-S理论的库仑分支维度公式。为了系统分析推迟到相关论文中，我们在这里确定了许多穿刺对分级库仑分支维度的贡献，在某些低秩情况下，甚至确定了全部贡献。然后，我们能够识别多种已知的4D$\mathcal{N}=2$超共形场论（SCFT）与扭曲$A_{2n}$理论，并重现了许多已知性质，例如某些Argyres-Douglas理论之间的S对偶性。 显示英文摘要

摘要： In this paper, we investigate the twisted $A_{2n}$ sector of class-S theories. Heretofore, the Coulomb branches of such theories have been poorly understood. In this, and a companion paper, we make progress in our understanding of them. In particular, we find a formula for the dimension of the Coulomb branch of any twisted $A_{2n}$ class-S theory. Deferring a systematic analysis to the companion paper, we here determine many contributions of punctures to the graded Coulomb branch dimensions, and in some low rank cases, all of them. We are then able to identify a variety of known 4d $\mathcal{N}=2$ SCFTs with twisted $A_{2n}$ theories, and reproduce many of their known properties, such as S-duality amongst certain Argyres-Douglas theories.
