Curvaton reheating and intermediate inflation in brane cosmology

In this paper, we study the curvaton reheating mechanism for an intermediate inflationary universe in brane world cosmology. In contrast to our previous work, we assume that when the universe enters the kination era, it is still in the high-energy regime. We then discuss, in detail, the new cosmological constraints on both the model parameters and the physical quantities. PACS Nos: 98.80.Cq, 11.25.-w Nous etudions ici le mecanisme de rechauffe pour un univers inflationniste intermediate en cosmologie d'un monde branaire. Contrairement a notre travail precedent, nous supposons qu'au moment d'entrer dans son ere cinetique, l'univers est encore en regime de haute energie. Nous discutons en detail les nouvelles contraintes cosmologiques sur les parametres du modele et sur les quantites physiques. [Traduit par la Redaction]
