CUORE, an array of 988 TeO2 bolometers, is about to be one of the most sensitive experiments searching for neutrinoless double-beta decay. Its sensitivity could be further improved by removing the background from α radioactivity. A few years ago it was pointed out that the signal from βs can be tagged by detecting the emitted Cherenkov light,...

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...

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...

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,...
