Generalized Global Symmetries [PDF]
Journal of High Energy Physics, 2015 A $q$-form global symmetry is a global symmetry for which the charged operators are of space-time dimension $q$; e.g. Wilson lines, surface defects, etc., and the charged excitations have $q$ spatial dimensions; e.g. strings, membranes, etc.

Bootstrapping 3D fermions with global symmetries [PDF]
Journal of High Energy Physics, 2018 We study the conformal bootstrap for 4-point functions of fermions 〈ψ i ψ j ψ k ψ ℓ 〉 in parity-preserving 3d CFTs, where ψ i transforms as a vector under an O(N ) global symmetry.

Global symmetries and partial confinement [PDF]
Journal of High Energy Physics, 2022 In gauge theories, spontaneous breaking of the centre symmetry provides a precise definition of deconfinement. In large-N gauge theories, evidence has emerged recently that between confined and deconfined phases a partially-deconfined phase can appear ...

Exploring 2-group global symmetries [PDF]
Journal of High Energy Physics, 2019 We analyze four-dimensional quantum field theories with continuous 2-group global symmetries. At the level of their charges, such symmetries are identical to a product of continuous flavor or spacetime symmetries with a 1-form global symmetry U(1) B (1) ,

Generalized global symmetries and holography [PDF]
SciPost Physics, 2018 We study the holographic duals of four-dimensional field theories with 1-form global symmetries, both discrete and continuous. Such higher-form global symmetries are associated with antisymmetric tensor gauge fields in the bulk.

Comments on Global Symmetries and Anomalies of 5d SCFTs. [PDF]
Commun Math Phys, 2022 We study various aspects of global symmetries in five-dimensional superconformal field theories. Whenever a supersymmetry-preserving relevant deformation is available, the infrared gauge theory description might exhibit a finite order mixed ’t Hooft ...

Duality, Generalized Global Symmetries and Jet Space Isometries [PDF]
Universe, 2021 We revisit universal features of duality in linear and nonlinear relativistic scalar and Abelian 1-form theories with single or multiple fields, which exhibit ordinary or generalized global symmetries.

Chern-Weil global symmetries and how quantum gravity avoids them [PDF]
Journal of High Energy Physics, 2021 We draw attention to a class of generalized global symmetries, which we call “Chern-Weil global symmetries,” that arise ubiquitously in gauge theories. The Noether currents of these Chern-Weil global symmetries are given by wedge products of gauge field ...

Global Symmetries, Local Symmetries and Groupoids [PDF]
Symmetry, 2021 Local symmetries are primarily defined in the case of spacetime, but several authors have defined them outside this context, sometimes with the help of groupoids. We show that, in many cases, local symmetries can be defined as global symmetries.

GRAVITY AND GLOBAL SYMMETRIES [PDF]
Physical Review D, 1995 There exists a widely spread notion that gravitational effects can strongly violate global symmetries. It may lead to many important consequences. We will argue, in particular, that nonperturbative gravitational effects in the axion theory lead to a ...
