  author={Mar Bastero-Gil and Vicente Di Clemente and Stephen F. King},
We discuss the potentially important rôle played by preheating in certain variants of the curvaton mechanism in which isocurvature perturbations of a D-flat (and F-flat) direction become converted to curvature perturbations during reheating. We analyse the transition from inflation to reheating in some detail, including the dynamics of the coupled curvaton… CONTINUE READING
