Description
Neutrino physics is one of the most exciting arena for a combined research in cosmology and particle physics. The evolution of the Cosmic Neutrino Background has a non-negligible impact on cosmological observables, allowing cosmology to provide information about neutrino properties. In this talk, I will review the main physical effects of relic neutrinos and summarise current constraints on and future sensitivities to their properties within the standard model framework. I will finally focus on massive neutrinos, highlighting complementarity between cosmological and laboratory searches, such as beta and neutrino less double-beta decay experiments.
