Conformal manifolds and 3d mirrors of Argyres-Douglas theories

Argyres-Douglas theories constitute an important class of superconformal field in $4$d. The main focus this paper is on two infinite families such theories, known as $D^b_p(\mathrm{SO}(2N))$ and $(A_m, D_n)$. We analyze depth their conformal manifolds. In doing so we encounter several $\mathcal{S}$ twisted $A_{\text{odd}}$, $A_{\text{even}}$ $D$ types associated with a sphere one irregular puncture regular puncture. These models include $D_p(G)$ $G$ non-simply-laced algebras. A number new properties are discussed detail, along SCFTs that arise from partially closing the Moreover, systematically present $3$d mirror also magnetic quivers, for $p \geq b$, D_n)$ arbitrary $m$ $n$. discuss reduction certain < where former arises gauging topological symmetries some $T^\sigma_\rho[\mathrm{SO}(2M)]$ not manifest Lagrangian description latter.
