New Limit on the NeutrinolessββDecay ofTe130

We report the present results of CUORICINO, a search for neutrinoless double-beta ($0\nu \beta \beta$) decay of ${}^{130}\mathrm{Te}$. The detector is an array of 62 ${\mathrm{TeO}}_2$ 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 $\sim 8\mathrm{mK}$ in the Gran Sasso Underground Laboratory. No evidence for ($0\nu \beta \beta$) decay was found and a new lower limit, $T_{1/2}^{0\nu }\ge 1.8\times {10}^{24}\mathrm{yr}$ (90% C.L.) is set, corresponding to $⟨m_{\nu }⟩\le 0.2$ to 1.1 eV, depending on the theoretical nuclear matrix elements used in the analysis.
