| dc.description.abstract | We study inflation in the alpha-attractor model under a non-slow-roll dynamics with an ansatz proposed by Gong & Sasaki of assuming N=N(phi). Under this approach, we construct a class of local shapes of inflaton potential that are different from the T-models. We find this type of inflationary scenario predicts an attractor at n_s~0.967 and r~0.00055. In our approach, the non-slow-roll inflaton dynamics are related to the $\alpha-$parameter which is the curvature of Kähler geometry in the SUGRA embedding of this model. | pt_PT |
