Description
It is important to understand not only the observational constraints on large field inflation, but also any possible theoretical constraints. Among the theoretical constraints, one could focus one's attention to Ultra-Violet (UV) sensitivity. In this talk, I shall present simple variations of the minimal extranatural inflation model of inflation which are completely consistent with CMB observations and have scalar potentials protected from unknown UV effects. Finally, I shall discuss the connections of this with the Weak Gravity Conjecture. Based on: Mansi Dhuria, Gaurav Goswami, and Jayanti Prasad, Phys. Rev. D 96, 083529 (2017).
