“…In CUORE, 988 TeO 2 crystals with natural 130 Te isotopic abundance and a 750 g average mass are operated simultaneously as source and bolometric detector for the decay. In this way, the 0νββ decay signature is a peak at the Q-value of the reaction (Q ββ , 2527.518 keV for 130 Te [7][8][9]). Bolometric crystals are characterized by an excellent energy resolution (∼0.2% Full Width at Half Maximum, FWHM) and a very low background at Q ββ , which is expected to be at the 10 -2 cts/(keV·kg·yr) level in CUORE [10].…”

We report a study of the CUORE sensitivity to neutrinoless double beta (0νββ) decay. We used a Bayesian analysis based on a toy Monte Carlo (MC) approach to extract the exclusion sensitivity to the 0νββ decay half-life (T 0ν 1/2 ) at 90% credibility interval (CI) -i.e. the interval containing the true value of T 0ν 1/2 with 90% probability -and the 3 σ discovery sensitivity. We consider various background levels and energy resolutions, and describe the influence of the data division in subsets with different background levels. If the background level and the energy resolution meet the expectation, CUORE will reach a 90% CI exclusion sensitivity of 2 · 10 25 year with 3 months, and 9 · 10 25 year with 5 years of live time. Under the same conditions, the discovery sensitivity after 3 months and 5 years will be 7 · 10 24 year and 4 · 10 25 year, respectively.

“…The Cryogenic Underground Observatory for Rare Events (CUORE) [6,7] is the latest and most massive in a family of bolometric detectors designed to search for the 0νββ decay of 130 Te (Q-value = 2528 keV [8][9][10]). The detector combines the excellent energy resolution achievable with the bolometric technique (∼5 keV at 2615 keV) with the exceptionally high natural abundance of 130 Te (34%).…”

We report on the measurement of the twoneutrino double-beta decay half-life of 130 Te with the CUORE-0 detector. From an exposure of 33.4 kg year of TeO 2 , the half-life is determined to be T 2ν 1/2 = [8.2 ± 0.2 (stat.) ± 0.6 (syst.)] × 10 20 year. This result is obtained after a detailed reconstruction of the sources responsible for the CUORE-0 counting rate, with a specific study of those contributing to the 130 Te neutrinoless double-beta decay region of interest.

“…Tellurium is an advantage in this instance because of the relatively high natural abundance (34.2% [7]) of the 0νββ candidate isotope, which means that enrichment is not necessary to achieve a reasonably large active mass. Also, the Q-value (around 2528 keV [8][9][10]) of the decay falls between the peak and the Compton edge of the 2615 keV gamma line of 208 Tl, the highest-energy gamma from the natural decay chains; this leaves a relatively clean window in which to look for the signal. Moreover crystals or TeO 2 can be grown to large size with low radioactive contamination [11].…”

Abstract. The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment to search for neutrinoless double beta decay (0νββ) in 130 Te and other rare processes. CUORE is a cryogenic detector composed of 988 TeO 2 bolometers for a total mass of about 741 kg. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts/(keV·kg·y) will be reached, in five years of data taking CUORE will have an half life sensitivity around 1 × 10 26 y at 90% C.L. As a first step towards CUORE a smaller experiment CUORE-0, constructed to test and demonstrate the performances expected for CUORE, has been assembled and is running. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented.
