#### Abstract

The Coulomb branch indices of Argyres–Douglas theories on $L(k, 1) \times S^1$ are recently identified with matrix elements of modular transforms of certain $2d$ vertex operator algebras in a particular limit. A one parameter generalization of the modular transformation matrices of $(2N + 3, 2)$ minimal models are proposed to compute the full Coulomb branch index of $(A_1, A_{2N})$ Argyres–Douglas theories on the same space. Moreover, M‑theory construction of these theories suggests direct connection to the refined Chern–Simons theory. The connection is made precise by showing how the modular transformation matrices of refined Chern–Simons theory are related to the proposed generalized ones for minimal models and the identification of Coulomb branch indices with the partition function of the refined Chern–Simons theory.
