| * ABSTRACT | |||||||
| In this talk I will introduce a scenario of multiple brane inflation. This model involves multiple degrees of freedom and each mode has its own sound speed parameter. As a consequence, the parameter space is dramatically enlarged and can easily fit to observations. Particularly, this model can give rise to an interesting mechanism of generating primordial curvature perturbations, which is so-called curvaton brane. I will introduce relevant phenomenological results of this scenario and compare it with traditional curvaton mechanism. |
