Duality and Global Symmetries [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 This is a general introduction to duality in field theories. The existence and breaking of global symmetries is used as a guideline to systematically prove duality between different field theories.

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.

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) ,

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.

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 ...

Global symmetries and partial confinement
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 ...

Strongly Interacting Light Dark Matter [PDF]
SciPost Physics, 2017 In the presence of approximate global symmetries that forbid relevant interactions, strongly coupled light Dark Matter (DM) can appear weakly coupled at small energy and generate a sizable relic abundance.

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.

Exactly Marginal Deformations and Global Symmetries [PDF]
Journal of High Energy Physics, 2010 We study the problem of finding exactly marginal deformations of N=1 superconformal field theories in four dimensions. We find that the only way a marginal chiral operator can become not exactly marginal is for it to combine with a conserved current ...
