heal.abstract We study the curvaton dynamics in brane-world cosmologies. Assuming that the inflaton field survives without decay after the end of inflation, we apply the curvaton reheating mechanism to the Randall-Sundrum model and to its curvature corrections: Gauss-Bonnet, induced gravity and combined Gauss-Bonnet and induced gravity cosmological models. In the case of chaotic inflation and requiring suppression of possible short-wavelength generated gravitational waves, we constrain the parameters of a successful curvaton brane-world cosmological model. If density perturbations are also generated by the curvaton field, then the fundamental five-dimensional mass could be much lower than the Planck mass. © 2006 IOP Publishing Ltd and SISSA. en
