Long distance behavior of O(N)-model correlators in de Sitter space and the resummation of secular terms

Abstract We analyze the long distance behavior of the two-point functions for an interacting scalar O(N) model in de Sitter spacetime. Following our previous work, this behavior is analyzed by analytic continuation of the Euclidean correlators, which are computed by treating the homogeneous zero mod...
