Abstract:
We report the present results of CUORICINO, a search for neutrinoless double-beta (0νββ) decay of 130Te. The detector is an array of 62 TeO2 bolometers with a total active mass of 40.7 kg. The array is cooled by a dilution refrigerator shielded from environmental radioactivity and energetic neutrons, operated at ∼8 mK in the Gran Sasso Underground Laboratory. No evidence for (0νββ) decay was found and a new lower limit, T1/20ν≥1.8×1024 yr (90% C.L.) is set, corresponding to ⟨mν⟩≤0.2 to 1.1 eV, depending on the theoretical nuclear matrix elements used in the analysis.
