Product SCFTs in Class-S

Jacques Distler, Behzat Ergun, Fei Yan

We develop a technique for counting the number of stress tensor multiplets in a 4D $N = 2$ SCFT. This provides a simple diagnostic for when an isolated (non-Lagrangian) SCF…

Line defect Schur indices, Verlinde algebras and $U (1)_{r}$ fixed points

Andrew Neitzke, Fei Yan

Given an $N = 2$ superconformal field theory, we reconsider the Schur index $I_{L} (q)$ in the presence of a half line defect $L$ . Recently Cordova-Gaiotto-Shao foun…
