CUORE (Cryogenic Underground Observatory for Rare Events) is a particle physics facility located at the Laboratori Nazionali del Gran Sasso in Italy. It uses a tellurium dioxide crystal bolometer-thermistor detector to search for neutrinoless double beta decay (0νββ) in 130Te.[1] Observing such decays would mean that neutrinos are their own antiparticles and Majorana fermions.[1]This is relevant to many topics in particle physics: lepton number conservation, nuclear structure, as well as neutrino masses and properties. CUORE searches for a spike in the tellurium decay spectrum around the known decay energy of Q = 2527.518±0.013 keV[4], that would be evidence of 0νββ events. The detector is expected to be sensitive enough to also be used in searches for axion signals and dark matter.

The CUORE collaboration involves physicists from several countries including the US and Italy,[5] and has published papers on the performance of various parts of the detector and simulation.[6] CUORE is primarily funded by the Istituto Nazionale di Fisica Nucleare (INFN) of Italy, the United States Department of Energy (DOE), and the National Science Foundation (NSF) of the United States.
In September 2014, CUORE researchers cooled a copper vessel inside the detector with a volume of one cubic meter to 6 mK for 15 days, setting a record for the lowest temperature in the known universe over such a large contiguous volume.[7] [8][9] [10]
