Probing the Nature of Neutrino Mass

The discovery of neutrino oscillation has shown that neutrinos have non-zero mass but the nature of neutrino mass, the absolute mass scale, and the ordering of the neutrino mass states remain unknown. Neutrinoless double beta decay (0νββ) is uniquely suited to probe the Majorana nature of neutrinos and determine the effective neutrino mass. CUORE, the Cryogenic Underground Observatory for Rare Events (CUORE) and its upgrade CUPID aim to search for 0νββ down to the level of the inverted mass ordering using the world’s largest bolometric detector. Project 8 represents a novel approach to directly measure the absolute neutrino mass using cyclotron radiation emission spectroscopy. In this talk. I will present the latest results from CUORE, the plans for CUPID, and the prospect for measuring the neutrino mass with Project 8.
