Gupta, Sujata and Malik, Karim A. and Wands, David (2004) Curvature and isocurvature pertubations in a three-fluid model of curvaton, decay. Physical Review D, 69 (6). ISSN 1550-7998Full text not available from this repository.
We study the evolution of the cosmological perturbations after inflation in curvaton models where the nonrelativistic curvaton decays into both radiation and a cold dark matter component. We calculate the primordial curvature and correlated isocurvature perturbations inherited by the radiation and cold dark matter after the curvaton has decayed. We give the transfer coefficient in terms of the initial curvaton density relative to the curvaton decay rate.
