Finite parts of inflationary loops
Guillermo Ballesteros, Jesús Gambín Egea, Flavio Riccardi
Abstract
A bstract We present a method for solving loop integrals in dimensional regularization that is particularly useful in the context of inflation. We apply this method to the calculation of the tensor power spectrum induced by scalar fluctuations in slow-roll inflation.
