GJC: Flavio Riccardi "Finite parts of inflationary loops"

Tuesday 17 Dec 2024, 13:00 → 14:00 Europe/Rome

Sala Cortini (Fermi)

The objective of this talk is to present a systematic approach for calculating loop corrections, including finite contributions, to the power spectrum in a cosmological setting. Particular emphasis will be placed on the renormalization procedure, comparing the results obtained using different regularization methods.
As an application, this method will be applied to a clear and straightforward case: the computation of the one-loop power spectrum for tensor modes generated by slow-roll inflationary dynamics.
