The Feynman Propagator and Correlation Functions in an Inflating Spacetime
Speaker(s): Jason Kumar
Abstract: We discuss the definition of the Feynman propagator in de Sitter space. We show that the ambiguities in the propagator zero-mode can be used to make sense of the behavior of low-momentum modes in an inflating space-time. We use this tool to calculate loop corrections to non-Gaussian correlation func... read more
