Description
In this talk I will present an exactly solvable theory on a fixed de Sitter spacetime that can be analyzed efficiently using Euclidean methods. I will then discuss the fully non-perturbative, all loop correlation function of gauge invariant operators and demonstrate many features endemic of quantum field theory in de Sitter space such as the appearance of late-time logarithm and their resummation. Time permitting, I will discuss how this theory allows us to entertain the idea of new de Sitter invariant vacuum states.
