“…The first CUORE physics results of 0 and 2 in 130 Te were obtained from the analysis of physics data collected in 2017 for 86.3 kg(TeO 2 ) year exposure. A total raw exposure of more than 400 kg year was already available in July 2019; updated results for 372.5 kg(TeO 2 ) year exposure (after the analysis selections) were released in December 2019 [22].…”

The cryogenic underground observatory for rare events (CUORE) is a cryogenic experiment searching for neutrinoless double beta decay (0) of 130 Te. The detector consists of an array of 988 TeO 2 crystals arranged in a compact cylindrical structure of 19 towers. We report the CUORE initial operations and optimization campaigns. We then present the CUORE results on 0 and 2 decay of 130 Te obtained from the analysis of the physics data acquired in 2017.

“…Up to now, there is a consensus that the highest sensitivity to small Majorana neutrino masses can be reached in experiments on the search of the L-violating neutrinoless double-β decay process (0νββ). Dozens of experiments around the world are seeking out a positive signal, and the most sensitive limits are obtained by GERDA-II [14] in 76 Ge, CUORE [15] in 130 Te and KAMLAND-Zen [16] in 136 Xe. An alternative to 0νββ is provided by the mechanism of neutrinoless double electron capture (0νECEC) [17], which actually corresponds to a virtual mixing between a nominally stable parent Z atom and a daughter ðZ − 2Þ Ã atom with two electron holes.…”

Absolute neutrino mass and the Dirac/Majorana distinction from the weak interaction of aggregate matter

The 2ν-mediated force has a range of microns, well beyond the atomic scale. The effective potential is built from the t-channel absorptive part of the scattering amplitude and depends on neutrino properties on shell. We demonstrate that neutral aggregate matter has a weak charge and calculate the matrix of six coherent charges for its interaction with definite-mass neutrinos. Near the range of the potential the neutrino pair is nonrelativistic, leading to observable absolute mass and Dirac/Majorana distinction via different r-dependence and violation of the weak equivalence principle.

“…An FWHM energy resolution of (7.7 ± 0.5) keV has been measured and in the region of interest the background level is (0.014 ± 0.002) counts keV −1 kg −1 y −1 [124], one order of magnitude lower than in CUORICINO.

Cosmogenic Activation in Double Beta Decay Experiments

Double beta decay is a very rare nuclear process and, therefore, experiments intended to detect it must be operated deep underground and in ultra-low background conditions. Long-lived radioisotopes produced by the previous exposure of materials to cosmic rays on the Earth’s surface or even underground can become problematic for the required sensitivity. Here, the studies developed to quantify and reduce the activation yields in detectors and materials used in the set-up of these experiments will be reviewed, considering target materials like germanium, tellurium and xenon together with other ones commonly used like copper, lead, stainless steel or argon. Calculations following very different approaches and measurements from irradiation experiments using beams or directly cosmic rays will be considered for relevant radioisotopes. The effect of cosmogenic activation in present and future double beta decay projects based on different types of detectors will be analyzed too.
