Strongly coupled sectors in inflation: gapless theories and unparticles
Abstract We compute correlation functions of the primordial density perturbations when they couple to a gapless, strongly coupled sector of spectator fields — “unparticles” — during inflation. We first derive a four-point function of conformally coupled scalars for all kinematic configurations in de...
