Status of the CUORE 0ν β β decay search — •Benjamin Schmidt for the CUORE collaboration — Institute for Nuclear and Particle Astrophysics, Lawrence Berkeley National Laboratory, Berkeley, CA, USA

Observation of neutrinoless double beta decay (0ν β β) would establish lepton number violation, would indicate that neutrinos are Majorana particles, and could provide information on the absolute neutrino mass scale. CUORE, the Cryogenic Underground Observatory for Rare Events, uses a cryogenic array of 988 TeO₂ bolometers to target the 0ν β β decay candidate isotope ¹³⁰Te. It is the first tonne-scale cryogenic bolometer experiment featuring a total detector mass of about 740 kg of natural tellurium. Recently the detector installation at the Laboratori Nazionali del Gran Sasso (LNGS) has been completed and data taking is scheduled to begin in early 2017. We will discuss the status of the CUORE experiment and present the most recent results from CUORE-0, a single-tower array of 52 crystals, operated at LNGS between 2013-2015.
