Description

Non-local field theoretic frameworks can provide ghost free renormalizable description of gravity. Recently it is shown that a non-local extension of Starobinsky gravity can consistently realize inflation and have interesting observational features in the three point functions of scalar perturbations. In this talk we will describe inflation with a scalar field having non-local kinetic term and discuss the observational consequences of non-locality. Specifically we will highlight the modifications in three point functions of scalar perturbations. Additionally, we will present a bouncing scenario from a non-local gravitational setup and discuss its observational consequences.
