November 12 - 18, 2017 — IESC,
The CMB from A to Z
challenges of the CMB as a cosmological probe
Probing secret interactions in the neutrino sector through CMB observations
Physics Department, University of Ferrara
|Abstract : In this talk I will show an approach to constrain non standard interactions in the neutrino sector.
I will first present the theoretical framework of pseudoscalar and
Fermi-like interacting neutrinos, then I will move on the constraints
obtained using cosmological data.
In particular I will show results, obtained using Planck 2013 and 2015
data, for a secret pseudoscalar interaction in the massless neutrino
sector and for a Femi-like secret interaction in the massive sterile
