Towards the non-perturbative cosmological bootstrap

Abstract We study quantum field theory on a de Sitter spacetime dS d+1 background. Our main tool is the Hilbert space decomposition in irreducible unitary representations of its isometry group SO(d + 1, 1). As the first application of the Hilbert space formalism, we recover the Källen-Lehmann spectr...
