Abstract

The bottom-up approach of the AdS/CFT correspondence leads to the study of field equations in an AdS₅ background and from their solutions to the determination of the hadronic mass spectrum. We extend the study to the equations of AdS₅ gravitons and determine from them the glueball spectrum. We propose an original presentation of the results which facilitates the comparison of the various models with the spectrum obtained by lattice QCD. This comparison allows to draw some phenomenological conclusions.
