Non-Gaussianities and tensor-to-scalar ratio in non-local R 2-like inflation
Abstract In this paper we will study R 2-like inflation in a non-local modification of gravity which contains quadratic in Ricci scalar and Weyl tensor terms with analytic infinite derivative form-factors in the action. It is known that the inflationary solution of the local R + R 2 gravity remains...
