Neutrino mass scale in the era of precision cosmology

Abstract

In this work, we study how recent cosmological datasets in combination with particle physics results are able to constrain the neutrino mass scale. In particular, we present current bounds on the electron neutrino mass m_β, the effective Majorana mass m_ββ and the total neutrino mass Σm_v and we discuss the sensitivity required to future experiments in order to address the issue of neutrino hierarchy.
