Non-Gaussianities in generalized non-local R 2-like inflation
Abstract In [1], a most general higher curvature non-local gravity action was derived that admits a particular R 2-like inflationary solution predicting the spectral index of primordial scalar perturbations n s N ≈ 1 − 1 2 $$ {n}_s(N)\approx 1-\frac{1}{2} $$ , where N is the number of e-folds before...
