New $$ \mathcal{N} $$ = 2 superconformal field theories from $$ \mathcal{S} $$-folds

Abstract

Abstract We study the four-dimensional $$ \mathcal{N} $$ N = 2 superconformal field theories that describe D3-branes probing the recently constructed $$ \mathcal{N} $$ N = 2 $$ \mathcal{S} $$ S -folds in F-theory. We introduce a novel, infinite class of superconformal field theories related to $$ \mathcal{S} $$ S -fold theories via partial Higgsing. We determine several properties of both the $$ \mathcal{S} $$ S -fold models and this new class of theories, including their central charges, Coulomb branch spectrum, and moduli spaces of vacua, by bringing to bear an array of field-theoretical techniques, to wit, torus-compactifications of six-dimensional $$ \mathcal{N} $$ N = (1, 0) theories, class $$ \mathcal{S} $$ S technology, and the SCFT/VOA correspondence.
