In this work we study the possibility that the recently discovered particle at the Large Hadron Collider (LHC) with similar properties to the ones of the Standard Model (SM) Higgs boson and a mass around 125 GeV could be related to the dilaton, the Goldstone boson that appears when scale invariance is spontaneously broken. We will focus on the Coleman-Weinberg (CW) mechanism, in which the mass term from the Higgs potential is turned oﬀ, thus obtaining a theory classically invariant under dilatations. It is due to quantum eﬀects that the spontaneous breaking of this symmetry occurs. We will study the viability of this scenario treating with the CW potential and doing numerical testing as well as proposing possible modiﬁcations of the SM
