*, Multiple field inflation with additional heavy fields,*

Current precision measurements of the cosmic microwave background radiation (CMB) provide compelling evidence for the paradigm of inflation. Simple single field inflation can fit the data well, but the precise microphysical origin of inflation remains unknown. We are interested in the case that single field inflation is an effective description of a more fundamental theory containing multiple scalar fields. Even if these extra degrees of freedom are all very heavy compared to the Hubble scale of inflation they still might influence the dynamics of the inflaton. This leads to features in the statistical properties of the temperature fluctuations in the CMB and deviations from the simple, single-field predictions. We discuss possible observational consequences and how future data might be able to detect heavy physics present during the epoch of inflation.
