A holographic realization of light dilatons

Abstract

We study a realization of light dilatons by considering Conformal Field Theories deformed by a nearly marginal operator $\mathcal{O}$. This is discussed in the holographic setup consisting of Renormalization Group flows that end on a soft wall. We obtain a mass formula for the dilaton as an average along the flow. Finally we discuss the holographic method to compute the condensate $⟨\mathcal{O}⟩$.
