Limits on the equation of state parameter for interacting dark energy |
Under the assumption that cold dark matter and dark energy interact with each other through a small coupling term, Q, we constrain the parameter space of the equation of state, w, of dark energy by imposing that the variation of the dark energy field since last scattering should not exceed Planck's mass. We use three parameterizations of w and two different expressions for Q. Our work extends previous ones. |
