Non Gaussianity of General Multiple-Field Inflationary Models
نویسندگان
چکیده
Using the “δN -formalism”, We obtain the expression of the non Gaussianity of multiple-field inflationary models with the nontrivial field-space metric. Further, we rewritten the result by using the slowrolling approximation. Finally, using our result, we calculate the nonlinear parameter of the racetrack inflationary model.

Primordial Non-Gaussianities of General Multiple Field Inflation
We perform a general study of the primordial scalar non-Gaussianities in multi-field inflationary models in Einstein gravity. We consider models governed by a Lagrangian which is a general function of the scalar fields and their first-order spacetime derivatives. We use δN formalism to relate scalar fields and the curvature perturbations. We calculate the explicit cubic-order perturbative actio...
متن کاملNon-Gaussianity and large-scale structure in a two-field inflationary model
Single-field inflationary models predict nearly Gaussian initial conditions, and hence a detection of non-Gaussianity would be a signature of the more complex inflationary scenarios. In this paper we study the effect on the cosmic microwave background and on large-scale structure from primordial nonGaussianity in a two-field inflationary model in which both the inflaton and curvaton contribute ...
متن کاملNon-Gaussianity, Spectral Index and Tensor Modes in Mixed Inflaton and Curvaton Models
We study non-Gaussianity, the spectral index of primordial scalar fluctuations and tensor modes in models where fluctuations from the inflaton and the curvaton can both contribute to the present cosmic density fluctuations. Even though simple single-field inflation models generate only tiny non-Gaussianity, if we consider such a mixed scenario, large non-Gaussianity can be produced. Furthermore...
متن کاملObservational Signatures and Non-Gaussianities of General Single Field Inflation
We perform a general study of primordial scalar non-Gaussianities in single field inflationary models. We consider models where the inflaton Lagrangian is an arbitrary function of the scalar field and its first derivative, and the sound speed is arbitrary. We find that under reasonable assumptions, the non-Gaussianity is completely determined by 5 parameters. In special limits of the parameter ...
متن کاملNon-Gaussianity after BICEP2.
We analyze primordial non-Gaussianity in single-field inflationary models when the tensor-to-scalar ratio is large. Our results show that detectable levels of non-Gaussianity f(NL) ∼ 50 are still possible in the simplest class of models described by the effective theory of inflation. However, the shape is very tightly constrained, making a sharp prediction that could be confirmed or falsified b...
