On the IR divergences in de Sitter space: loops, resummation and the semi-classical wavefunction

Abstract In this paper, we revisit the infrared (IR) divergences in de Sitter (dS) space using the wavefunction method, and explicitly explore how the resummation of higher-order loops leads to the stochastic formalism. In light of recent developments of the cosmological bootstrap, we track the beha...
