Coupling of Higher Spin Gauge Fields to a Scalar Field in $AdS_{d+1}$ and their Holographic Images in the $d$-Dimensional Sigma Model

Autor: Leonhardt, T., Manvelyan, R., Ruehl, W.

The three-point functions of two scalar fields $\sigma$ and the higher spin field $h^{(\ell)}$ of HS(4) on the one side and of their proposed holographic images $\alpha$ and $\mathcal{J^{(\ell)}}$ of the minimal conformal O(N) sigma model of dimensio

Report

On the proposed AdS dual of the critical O(N) sigma model for any dimension 2

Autor: Leonhardt, T., Meziane, A., Ruehl, W.

Publikováno v: Phys.Lett. B555 (2003) 271-278

We evaluate the 4-point function of the auxiliary field in the critical O(N) sigma model at O(1/N) and show that it describes the exchange of tensor currents of arbitrary even rank l>0. These are dual to tensor gauge fields of the same rank in the Ad

Report

Composite fields, generalized hypergeometric functions and the $U(1)_Y$ symmetry in the AdS/CFT correspondence

Autor: Hoffmann, L., Leonhardt, T., Mesref, L., Ruhl, W.

We discuss the concept of composite fields in flat CFT as well as in the context of AdS/CFT. Furthermore we show how to represent Green functions using generalized hypergeometric functions and apply these techniques to four-point functions. Finally w
