Beyond the Starobinsky model for inflation

30 Apr 2020 Cheong Dhong Yeon Lee Hyun Min Park Seong Chan

We single out the Starobinsky model and its extensions among generic $f(R)$ gravity as attractors at large field values for chaotic inflation. Treating a $R^3$ curvature term as a perturbation of the Starobinsky model, we impose the phenomenological bounds on the additional term satisfying the successful inflationary predictions...
