A bstract Five-and four-dimensional superconformal field theories with eight supercharges
arise from canonical threefold singularities in M-theory and Type IIB string theory …

Starting with a gentle approach to the Alday–Gaiotto–Tachikawa (AGT) correspondence
from its 6d origin, these notes provide a wide (albeit shallow) survey of the literature on …

We determine the structure of 1-form symmetries for all 4d\(\mathcal {N}\)= 2 theories that
have a geometric engineering in terms of type IIB string theory on isolated hypersurface …

We determine the 1-form symmetry group for any 4d N= 2 class S theory constructed by
compactifying a 6d N=(2, 0) SCFT on a Riemann surface with arbitrary regular untwisted and …

We propose the first explicit holographic duals for a class of superconformal field theories of
Argyres-Douglas type, which are inherently strongly coupled and provide a window onto …

A bstract We initiate a study of the holographic duals of a class of four-dimensional\(\mathcal
{N}\)= 2 superconformal field theories that are engineered by wrapping M5-branes on a …

The Higgs branch of 4D N= 2 superconformal field theories can be analyzed via the Hilbert
series of the Higgs branch or, in special cases, by computing the Hall-Littlewood index. For …

A bstract We refine our previous proposal [1-3] for systematically classifying 4d rank-
1\(\mathcal {N}\)= 2 SCFTs by constructing their possible Coulomb branch geometries. Four …

A bstract We study the defect groups of\({D} _p^ b\)(G) theories using geometric engineering
and BPS quivers. In the simple case when b= h∨(G), we use the BPS quivers of the theory …

A bstract Argyres-Douglas (AD) theories constitute an infinite class of superconformal field
theories in four dimensions with a number of interesting properties. We study several new …
