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 …

A bstract We construct a large class of Argyres-Douglas type theories by compactifying six
dimensional (2, 0) AN− 1 theory on a Riemann surface with irregular singularities. We give 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 study the full moduli space of vacua of 6d worldvolume SCFTs on M5 branes
probing an A-type singularity, focusing on the geometric incarnation of the discrete gauging …

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 …

A bstract We continue the study of Lagrangian descriptions of\(\mathcal {N}= 2\) Argyres-
Douglas theories. We use our recent interpretation in terms of sequential confinement to …

A bstract We carry out a systematic study of 4d\(\mathcal {N}\)= 2 preserving S-folds of F-
theory 7-branes and the worldvolume theories on D3-branes probing them. They consist of …

We propose a general way to complete supersymmetric theories with operators below the
unitarity bound, adding gauge-singlet fields that enforce the decoupling of such operators …

A bstract Argyres-Douglas theories constitute an important class of superconformal field
theories in 4d. The main focus of this paper is on two infinite families of such theories, known …

A bstract We describe a procedure for classifying 4D\(\mathcal {N}\)= 2 superconformal
theories of the type introduced by Davide Gaiotto. Any punctured curve, C, on which the 6D …
