Description
Inflationary models based on particle physics naturally involve multiple fields in addition to the inflaton field. Consequently these multiple fields may contribute to inflaton correlation functions via loop corrections. We study the quantum corrections to the inflaton two-point correlation functions due to massive scalar and fermion fields, employing the Schwinger-Keldysh formalism. We shall first describe the model and the generic framework. We then discuss time-dependent features of the primordial power spectrum.
