Abstract
Subject headings
Close
- Inflation is the leading paradigm for explaining the origin of primordial density perturbations. However many open questions remain, in particular whether one or more scalar fields were present during inflation and how they contributed to the primordial density perturbation. We propose a new observational test of whether multiple fields or only one (not necessarily the inflaton) generated the perturbations. We show that our test, relating the bispectrum and trispectrum, is protected against loop corrections at all orders, unlike previous relations. DOI: 10.1103/PhysRevD.87.043512
