A scale invariant model containing dilaton ϕ and dust (as a model of matter) is studied where the shift symmetry ϕ → ϕ + const. is spontaneously broken at the classical level due to intrinsic features of the model. The dilaton to matter coupling “constant”f appears to be dependent of the matter density. In normal conditions, i.e. when the matter energy density is many orders of magnitude larger than the dilaton contribution to the dark energy density, f becomes less than the ratio of the “mass… Expand
