• "The aim is to use the detector to try to observe a theoretical atomic event called neutrinoless double-beta decay - a radioactive process whereby an atomic nucleus releases two electrons and no neutrinos."
• "The committee recommends that the properties of neutrinos be determined through a well-coordinated, staged program of experiments developed with international planning and cooperation. • A phased program of searches for the nature of neutrino mass (using neutrinoless double beta decay) should be pursued with high priority. • DOE and NSF should invite international partners to initiate a multiparty study to explore the feasibility of joint rather than parallel efforts in accelerator-based neutrino experiments."
• "CUORE scientists will wait for neutrinoless double-beta decay to happen in a 750-kilogram cube of tellurium dioxide placed under 1,400 metres of rock at the Gran Sasso laboratory."
