On primordial trispectrum from exchanging scalar modes in general multiple field inflationary models
arXiv:1009.1311 · doi:10.1088/1475-7516/2010/11/035
Abstract
We make an complementary investigation of the primordial trispectrum from exchanging intermediate scalar modes in multi-field inflation models with generalized kinetic terms. Together with the calculation of irreducible contributions to the primordial trispectrum in Ref.[103], we give the full leading-order primordial trispectrum in generalized multi-field models.
