Résumé : 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 sector. |
