Supersymmetric hybrid inflation in the braneworld scenario

الأصل · EN

In this paper we reconsider the supersymmetric hybrid inflation in the context of the braneworld scenario. The observational bounds are satisfied with an inflationary energy scale μ≃ 4× 10⁻⁴Mₚ, without any fine-tuning of the coupling parameter, provided that the five-dimensional Planck scale is M₅< 2× 10⁻³Mₚ. We have also obtained an upper bound on the the brane tension.
