| Summary:

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 and obtain one-loop corrections to $n$-point meson
correlators with arbitrary operator dimensions. We show that these corrections
can be resumed into generating functions which exhibit emergent 8d structures
similar to the ones previously observed at strong coupling via AdS/CFT. These
structures of the $mathcal{N}=2$ theories also resemble the hidden 10d
structures in 4d $mathcal{N}=4$ SYM.
