Resumo(s)
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.
