The holographic model of QCD includes a static dilaton background field. We study the constraints on the masses coming from perturbing the dilaton field and the geometry of the bulk.Talk given at the International Workshop on Quantum Chromodynamics: QCD@Work 2007, Martina Franca, Italy, 16-20 June 2007High Energy Physics - Phenomenologytext
