Next-generation experiments searching for neutrinoless double-beta decay must be sensitive to a Majorana neutrino mass as low as 10 meV. CUORE, an array of 988 TeO2 bolometers being commissioned at Laboratori Nazionali del Gran Sasso, features an expected sensitivity of 50130 meV at 90 % C.L. The background is expected to be dominated bya...

In the view of exploring the inverted hierarchy region future experiments investigating the neutrinoless double beta decay have to demand for detectors with excellent energy resolution and zero background in the energy region of interest. Cryogenic scintillating bolometers are very suitable detectors for this task since they provide particle...

The LUCIFER project aims at deploying the first array of enriched scintillating bolometers for the investigation of neutrinoless double-beta decay of (Formula presented.). The matrix which embeds the source is an array of ZnSe crystals, where enriched (Formula presented.) is used as decay isotope. The radiopurity of the initial components...

Cryogenic calorimeters are currently used by experiments searching for neutrino-less double beta decay (0νββ). The sensitivity of these experiments is limited by the background coming from α radioactive contaminations. This background can be rejected exploiting the simultaneous readout of light and heat in scintillating cryogenic calorimeters,...

The CUPID-0 detector hosted at the Laboratori Nazionali del Gran Sasso, Italy, is the first large array of enriched scintillating cryogenic detectors for the investigation of82Se neutrinoless double-beta decay (0). CUPID-0 aims at measuring a background index in the region of interest (RoI) for 0at the level of 10- 3 counts/(keV kg years), the...

The CUPID-0 experiment searches for double beta decay using cryogenic calorimeters with double (heat and light) read-out. The detector, consisting of 24 ZnSe crystals 95% enriched in 82 Se and two natural ZnSe crystals, started data-taking in 2017 at Laboratori Nazionali del Gran Sasso. We present the search for the neutrino-less double beta...

The suppression of spurious events in the region of interest for neutrinoless double beta decay will play a major role in next generation experiments. The background of detectors based on the technology of cryogenic calorimeters is expected to be dominated by α particles, that could be disentangled from double beta decay signals by exploiting...

We present the search for Lorentz violation in the double beta decay of Se-82 with CUPID-0, using an exposure of 9.95 kg x yr. We found no evidence for the searched signal and set a limit on the isotropic components of the Lorentz violating coefficient of (a) over circle ((3))(of) < 4.1 x 10(-6) GeV (90% credible interval). This results is...

CUPID-0 is an array of 24 Zn82Se scintillating bolometers used to search for the 0νββ decay of 82Se. It is the first large mass 0νββ experiment exploiting a double read-out technique: the phonon signal to accurately measure particle energies and the light signal to reject the α-induced background. Its success might open the road to a next...
