Abstract Six-dimensional (6D) superconformal field theories (SCFTs) occupy a central place
in the study of quantum field theories encountered in high energy theory. This article reviews …

The modern approach to m‐form global symmetries in ad‐dimensional quantum field theory
(QFT) entails specifying dimension d− m− 1 dm-1 topological generalized symmetry …

R7-branes are a class of recently discovered nonsupersymmetric real codimension-two
duality defects in type IIB string theory predicted by the swampland cobordism conjecture …

Orbifold singularities of M-theory constitute the building blocks of a broad class of
supersymmetric quantum field theories (SQFTs). In this paper we show how the local data of …

A bstract We describe general methods for determining higher-form symmetry groups of
known 5d and 6d superconformal field theories (SCFTs), and 6d little string theories (LSTs) …

Within the framework of relative and absolute quantum field theories (QFTs), we present a
general formalism for understanding polarizations of the intermediate defect group and …

The center-flavor symmetry of a gauge theory specifies the global form of consistent gauge
and flavor bundle background field configurations. For 6D gauge theories which arise from a …

According to a conjecture, all 5 d SCFTs should be obtainable by rank-preserving RG flows
of 6 d SCFTs compactified on a circle possibly twisted by a background for the discrete …

We determine the 2-group structure constants for all the six-dimensional little string theories
(LSTs) geometrically engineered in F-theory without frozen singularities. We use this result …

A bstract We begin a study of the Higgs branch of six-dimensional (1, 0) little string theories
governing the worldvolumes of heterotic ALE instantons. We give a description of this space …
