Abstract

We consider the linear growth of matter perturbations on low redshifts in a specific f(R) dark energy (DE) model. We introduce a new parameterization for the growth factor γ(z) and show that for chosen parameters, this factor is clearly distinct from the one in ACDM and from results in other DE models. This may be an observational signature for f(R) models.
