“…Nevertheless, the trace of the current still decouples onshell as it should [24]. For the so-called "triplet" arising from the open string leading Regge trajectory [46,47,[49][50][51][52][53] (see also [10,23]), the situation is more subtle: although traceful conserved currents can indeed source the symmetric tensor field, only the traceless component of the currents studied here leads to genuine minimal interactions. 2 The kth trace of the current of rank r is a current of rank r − 2k (lower than r) and contains r derivatives.…”

Cubic couplings between a complex scalar field and a tower of symmetric tensor gauge fields of all ranks are investigated on any constant curvature spacetime of dimension d 3. Following Noether's method, the gauge fields interact with the scalar field via minimal coupling to the conserved currents. A symmetric conserved current, bilinear in the scalar field and containing up to r derivatives, is obtained for any rank r 1 from its flat spacetime counterpart in dimension d + 1, via a radial dimensional reduction valid precisely for the mass-square domain of unitarity in (anti) de Sitter spacetime of dimension d. The infinite collection of conserved currents and cubic vertices are summarized in a compact form by making use of generating functions and of the Weyl/Wigner quantization on constant curvature spaces.

“…Hence, only the spectrum of the theory and the quadratic terms in the action are of relevance to us. The quadratic action for higher-spin fields has already been worked out in an arbitrary dimensional AdS spacetime [26,27] (also see the related work [28,29] 4 ). We shall briefly recollect the main elements of the story.…”

Abstract:We calculate the one-loop partition function for a massless arbitrary-spin field on quotients of a general dimensional AdS background using the results of arXiv:1103.3627. We use these results to compute the one-loop partition function for a Vasiliev theory in AdS 5 . An interesting form of the answer, suggestive of a vacuum character of an enhanced symmetry algebra is obtained. We also observe a close connection between the partition function for this Vasiliev theory and the d-dimensional MacMahon function. * rgupta AT nikhef DOT nl † shailesh AT hri DOT res DOT in

“…Indeed, the resemblance between the spectrum of massless fields (1.4) and the tensionless limit of the leading flat-space Regge trajectory [23,66,60,67] can be made into a more precise correspondence, which includes massive multi-singletons and higher trajectories, by using supersymmetry and holography arguments [68,69,37,40,70]. Clearly, this motivates establishing a more direct link between the phase-space approach and the tensionless limit of (bosonic) p-branes in anti-de Sitter spacetime.…”

We examine p-branes in AdS D in two limits where they exhibit partonic behavior: rotating branes with energy concentrated to cusp-like solitons; tensionless branes with energy distributed over singletonic partons on the Dirac hypercone. Evidence for a smooth transition from cusps to partons is found. First, each cusp yields D − 2 normal-coordinate bound states with protected frequencies (for p > 2 there are additional bound states); and can moreover be related to a short open p-brane whose tension diverges at the AdS boundary leading to a decoupled singular CFT at the "brane at the end-of-the-universe". Second, discretizing the closed p-brane and keeping the number N of discrete partons finite yields an sp(2N )-gauged phase-space sigma model giving rise to symmetrized Ntupletons of the minimal higher-spin algebra ho 0 (D − 1, 2) ⊃ so(D − 1, 2). The continuum limit leads to a 2d chiral sp(2)-gauged sigma model which is critical in D = 7; equivalentá la Bars-Vasiliev to an su(2)-gauged spinor string; and furthermore dual to a WZW model in turn containing a topological so(6, 2) −2 /( so(6) ⊕ so(2)) −2 coset model with a chiral ring generated by singleton-valued weight-0 spin fields. Moreover, the two-parton truncation can be linked via a reformulationá la Cattaneo-Felder-Kontsevich to a topological open string on the phase space of the D-dimensional Dirac hypercone. We present evidence that a suitable deformation of the open string leads to the Vasiliev equations based on vector oscillators and weak sp(2)-projection. Geometrically, the bi-locality reflects broken boundary-singleton worldlines, while Vasiliev's intertwiner κ can be seen to relate T and R-ordered deformations of the boundary and the bulk of the worldsheet, respectively.
