Consistency of DBI-inspired Dinkic Inflation with Observational Data |
Abstract |
In this paper, a new kind of inflation model was used, which has the interesting property that its perturbation equation of motion gets a correction of k^4, due to the non-linearity of the kinetic term. Nonetheless, the scale-invariance of the power spectrum remains valid, both in large-k and small-k limits. we investigate in detail the perturbed parameters including slow-roll parameters, number of e-folds, spectral index, the index running and the tensor/scalar ratio in this model, especially on the potential-driven case. The results are compared to the current observational data. In this case, we also discuss the tensor spectrum, which is expected to be tested by the future observations on primordial gravitational waves. |
