A∞ algebras from slightly broken higher spin symmetries [PDF]

Journal of High Energy Physics, 2019
Abstract We define a class of A ∞-algebras that are obtained by deformations of higher spin symmetries. While higher spin symmetries of a free CFT form an associative algebra, the slightly broken higher spin symmetries give rise to a minimal A ∞-algebra extending the associative one.

On asymptotic symmetries in higher dimensions for any spin [PDF]

Journal of High Energy Physics, 2020
AbstractWe investigate asymptotic symmetries in flat backgrounds of dimension higher than or equal to four. For spin two we provide the counterpart of the extended BMS transformations found by Campiglia and Laddha in four-dimensional Minkowski space. We then identify higher-spin supertranslations and generalised superrotations in any dimension.

Metaplectic representation and ordering (in)dependence in Vasiliev’s higher spin gravity

Journal of High Energy Physics, 2022
We investigate the formulation of Vasiliev’s four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering.

Higher spin fields with mixed symmetry

Physics Letters B, 1986
Abstract Gauge invariant and gauge fixed BRS invariant actions are constructed in arbitrary dimensions for free massless integer spin fields carrying mixed representations of the Lorentz group described by Young tableaux (2, 1, 1, …, 1)n. The complete ghost spectrum is deduced by demanding nilpotency of the BRS transformations and leads to a correct ...

Differential contracting homotopy in higher-spin theory

Journal of High Energy Physics, 2023
A new efficient approach to the analysis of nonlinear higher-spin equations, that treats democratically auxiliary spinor variables Z A and integration homotopy parameters in the non-linear vertices of the higher-spin theory, is developed.

Entanglement Properties of a Higher-Integer-Spin AKLT Model with Quantum Group Symmetry [PDF]

, 2012
We study the entanglement properties of a higher-integer-spin Affleck-Kennedy-Lieb-Tasaki model with quantum group symmetry in the periodic boundary condition.

Mixed-symmetry multiplets and higher-spin curvatures [PDF]

Journal of Physics A: Mathematical and Theoretical, 2015
We study the higher-derivative equations for gauge potentials of arbitrary mixed-symmetry type obtained by setting to zero the divergences of the corresponding curvature tensors. We show that they propagate the same reducible multiplets as the Maxwell-like second-order equations for gauge fields subject to constrained gauge transformations.

Spinal Cord Infarction Versus Idiopathic Transverse Myelitis: Clinical, Radiological, and Functional Insights From a Retrospective Cohort Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Spinal cord infarction (SCI) is a rare but devastating myelopathy, characterized by a high disability rate and an unfavorable prognosis. It has often been underdiagnosed and misdiagnosed as idiopathic transverse myelitis (ITM). This study aimed to describe the clinical features, radiological biomarkers, treatments, and functional ...

Spontaneous symmetry breaking and Nambu–Goldstone bosons in quantum many-body systems

, 2010
Spontaneous symmetry breaking is a general principle that constitutes the underlying concept of a vast number of physical phenomena ranging from ferromagnetism and superconductivity in condensed matter physics to the Higgs mechanism in the standard model

On massive higher spins and gravity. Part II. Spin 3

Journal of High Energy Physics
In this paper, we continue our investigation of gravitational interactions for massive higher spins, extending our recent work on massive spin 5/2 to massive spin 3, including its massless and partially massless limits.
