SEMINAR - Inflation, non-Gaussianity and conformal symmetries

Wednesday December 5th 2012, 2:30 pm - Seminar room

Speaker: Toni Riotto (Geneva University)

Abstract: Non-Gaussianity, i.e. the non-Gaussian contributions to the correlations of the cosmological fluctuations, is an important probe of the physics of inflation.

We will show that the conformal symmetries present during the de Sitter epoch provide a very powerful method to characterize the non-Gaussianity generated during inflation in a model-independent way.
