On z-dominance, shift symmetry and spin locality in higher-spin theory

چکیده

A bstract The paper aims at the qualitative criterion of higher-spin locality. Perturbative analysis Vasiliev equations gives rise to so-called z -dominated non-localities which nevertheless disappear from interaction vertices leaving final result spin-local in all known cases. This has led one -dominance conjecture that suggests universality observed cancellations. Here we specify conditions include observation shift symmetry and prove validity this recently proposed conjecture. We also define a class shift-symmetric field redefinitions is argued be admissible with respect spin-locality.

Higher Spin Symmetry and N = 4 SYM

We assemble the spectrum of single-trace operators in free N = 4 SU (N) SYM theory into irreducible representations of the Higher Spin symmetry algebra hs(2, 2|4). Higher Spin representations or YT-pletons are associated to Young tableaux (YT) corresponding to representations of the symmetric group compatible with the cyclicity of color traces. After turning on interactions g YM = 0, YT-pletons...

Irreversibility and Higher-spin Conformal Field Theory

I discuss the properties of the central charges c and a for higher-derivative and higher-spin theories (spin 2 included). Ordinary gravity does not admit a straightforward identification of c and a in the trace anomaly, because it is not conformal. On the other hand, higherderivative theories can be conformal, but have negative c and a. A third possibility is to consider higher-spin conformal f...

Precision spectroscopy and higher spin symmetry in the ABJM model

We revisit Kaluza-Klein compactification of 11-d supergravity on S/Zk using group theory techniques that may find application in other flux vacua with internal coset spaces. Among the SO(2) neutral states, we identify marginal deformations and fields that couple to the recently discussed world-sheet instanton of Type IIA on CP3. We also discuss charged states, dual to monopole operators, and th...

Higher spin symmetry ( breaking ) in N = 4 SYM and holography ∗

I concisely review the results of [1–3] that shed some light on " La Grande Bouffe " 1 , the pantagruelic Higgs mechanism, whereby HS gauge fields in the AdS bulk eat lower spin Goldstone fields, and on its holographic implications such as the emergence of anomalous dimensions in the boundary N=4 SYM theory. Formulating the dynamics of higher spin (HS) fields is a long standing problem, see e.g...

Symmetry, spin-orbit interactions, and spin anisotropies.

The origins of anisotropy in the effective spin Hamiltonian, describing the ground manifold of Hubbard models with spin-orbit interactions, are critically discussed. For tetragonal symmetry, we show exactly that spin anisotropy can arise only if one includes both spin-orbit and Coulomb exchange interactions. For lower symmetries, additional anisotropies arise from terms which were hitherto negl...
