Neutrino mass eigenstates and their ordering: A Bayesian approach

Abstract

One of the not-yet determined properties of neutrinos is the ordering of their mass eigenstates. We combine the available data from neutrino oscillations, neutrinoless double beta decay and Cosmic Microwave Background observations to derive robust constraints on the mass ordering in a Bayesian context. This work is based on the paper by Gariazzo S. et al., JCAP, 03 (2018) 011.
