  1. Cryogenic Underground Observatory for Rare Events This experiment looks very promising for detection of neutrinoless double-beta decay (A,Z)→(A,Z+2)+2e- The CUORE Experiment For The Search Of 0νββ DecayLucia Cartegni

  2. Experimental Setup • TeO2 bolometers • T=10 mK • Te-130 isotopic abundance ~34% • ββ peak ~2.5 MeV • Energy resolution ~8keV • Total mass ~750 kg

  3. Underground Low natural radioactivity Nitrogen atmosphere Roman lead shields Polyethylene shields Faraday cage Materials shipped by sea Clean surfaces →Background ~0.2 counts/(keV kg year) CUORICINO experiment (~40 kg) Lower limit for lifetime ~1.8x1024 years Neutrino mass ~0.2-1.1 eV Background Reduction First Results
