Neutrino Properties and the Cosmological Tensions in the $\Lambda$CDM Model

S. Gariazzo
To appear in the Proceedings of the 15th Marcel Grossmann Meeting, parallel session CM4 (Tensions on LCDM cosmological model and model-independent constraints).
arXiv:1812.00638 [hep-ph].

Abstract:
In this talk I will review the current status of the constraints on the neutrino properties from cosmological measurements, with a particular focus on their mass and effective number. I will also discuss the existing tensions within the context of the \LambdaCDM model, including the discrepancies on the Hubble parameter and on the matter fluctuations at small scales, and how neutrinos could help to alleviate the aforementioned problems.
