摘要: We investigate the parameter spaces of hybrid inflation model with special attention paid to dynamics waterfall field and curvature perturbations induced from its quantum fluctuations. Depending on inflaton value at time phase transition sharpness can have multiple extended stages. find that for models mild perturbation is too large satisfy COBE normalization. space where fluctuations vary between results standard obtained here.
