Meson correlators in 4d $\mathcal{N}=2$ SCFTs and hints for 8d structures at weak coupling

Xi-Er Du, Zhongjie Huang, Bo Wang +2

We study correlators of $\frac{1}{2}$-BPS mesons in two examples of 4d SQCDs with $\mathcal{N}=2$ superconformal symmetry in the planar limit. We focus on the weakly coupled regime…
