Non-Gaussianities and tensor-to-scalar ratio in non-local R 2-like inflation

Koshelev A.S.; Kumar K.S.; Mazumdar A.; Starobinsky A.A. (2020)

© 2020, The Author(s). In this paper we will study R2-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 ...
Occurrence of exact R 2 inflation in non-local UV-complete gravity

Koshelev A.; Modesto L.; Rachwal L.; Starobinsky A. (2016)

© 2016, The Author(s).The R + R2, shortly named “R2” (“Starobinsky”) inflationary model, represents a fully consistent example of a one-parameter inflationary scenario. This model has a “graceful exit” from inflation and ...
R2inflation to probe non-perturbative quantum gravity

Unknown author (2018)

© 2018, The Author(s). It is natural to expect a consistent inflationary model of the very early Universe to be an effective theory of quantum gravity, at least at energies much less than the Planck one. For the moment, R ...
