The couplings of the Standard Model sector to scale invariant degrees of freedom can open the possibility to search for dark photons (DP). The decay of the Higgs-like scalar boson into a photon and DP is studied. The latter is mediated by the derivative of the scalar dilaton, emerging of which is provided by spontaneous breaking of scale symmetry. The limits are set on the DP mass, the mixing strength between the photon and DP.
