Weak gravity conjecture constraints on inflation

Abstract

We consider the gravitational correction to the coupling of the scalar fields. Weak gravity conjecture says that the gravitational correction to the running of scalar coupling should be less than the contribution from scalar fields. For instance, a new scale $\Lambda ={\lambda }_4^{1/2}{M}_p$ sets a UV cutoff on the validity of the effective ${\lambda }_4{\varphi }^4$ theory. Furthermore, this conjecture implies a possible constraint on the inflation model, e.g. the chaotic inflation model might be in the swampland.
