The CUORE experiment, a ton-scale cryogenic bolometer array, recently began operation at the Laboratori Nazionali del Gran Sasso in Italy. array represents significant advancement this technology, and work we apply it for first time to high-sensitivity search lepton-number--violating process: $^{130}$Te neutrinoless double-beta decay. Examining total TeO$_2$ exposure of 86.3 kg$\cdot$yr, characterized by an effective energy resolution (7.7 $\pm$ 0.5) keV FWHM background region interest...

Abstract The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from symmetric theory of fermions proposed by Ettore Majorana in 1937 1 . Given profound consequences such neutrinos, which is a potential explanation for matter–antimatter asymmetry universe via leptogenesis 2 , nature commands intense experimental scrutiny globally; one primary probes neutrinoless double beta (0 νββ ) decay. Here we show results search 0 decay 130...

Neutrinoless double beta decay ( $$0\nu \beta $$ ) is one of the most sensitive probes for physics beyond Standard Model, providing unique information on nature neutrinos. In this paper we review status and outlook bolometric searches. We summarize recent advances in background suppression demonstrated using bolometers with simultaneous readout heat light signals. simulate several configurations a future CUORE-like bolometer array which would utilize these improvements present sensitivity...

Abstract Future liquid-argon DarkSide-20k and Argo detectors, designed for direct dark matter search, will be sensitive also to core-collapse supernova neutrinos, via coherent elastic neutrino-nucleus scattering. This interaction channel is flavor-insensitive with a high-cross section, enabling high-statistics neutrino detection target masses of ∼50 t ∼360 respectively. Thanks the low-energy threshold ∼0.5 keV nr achievable by exploiting ionization channel, have potential discover bursts...
