We study the analytic properties of tree-level wavefunction coefficients in quaside Sitter space. We focus on theories which spontaneously break dS boost symmetries and can produce significant non-Gaussianities. The corresponding inflationary correlators are (approximately) scale invariant, but are not invariant under the full conformal group. We derive cutting rules and dispersion formulas for the late-time wavefunction coefficients by using factorization and analyticity properties of the dS… Expand
Analyticity and Unitarity for Cosmological Correlators
We study the fundamentals of quantum field theory on a rigid de Sitter space. We show that the perturbative expansion of late-time correlation functions to all orders can be equivalently generated byExpand
Towards the non-perturbative cosmological bootstrap
We study Quantum Field Theory (QFT) on a background de Sitter spacetime dSd+1. Our main tool is the Hilbert space decomposition in irreducible unitarity representations of its isometry group SO(d +Expand
Positivity and Geometric Function Theory Constraints on Pion Scattering
This paper presents the fascinating correspondence between the geometric function theory and the scattering amplitudes with O(N) global symmetry. A crucial ingredient to show such correspondence is aExpand
