Large order behavior near the AD point: the case of $\mathcal{N}=2$, $su(2)$, $N_f=2$

Chuan-Tsung Chan, Hiroshi Itoyama, Reiji Yoshioka

A non-perturbative effect in $\hat{I}º$ (renormalized string coupling) obtained from the large order behavior in the vicinity of the prototypical Argyres-Douglas critical point of $su(2)…
