[en] Thanks to the excellent energy resolution, high efficiency and versatility, bolometric detectors are primed for the search of neutrinoless double-beta decay (0νDBD). The most advanced bolometric experiment, CUORE, is studying the 0νDBD of "1"3"0Te using a 741 kg array of TeO_2 crystals. CUORE points to a 90% CL sensitivity on the half-life of 0νDBD of 9.5 × 10"2"5 yr in 5 yr, corresponding to an upper limit on the neutrino Majorana mass of 50–130 meV. This sensitivity will allow to touch, but not to explore, the region corresponding to the inverted hierarchy mass scenario. In this document I present the status of CUORE and the possible upgrades of the bolometric technology in view of a next generation experiment.

[en] This paper introduces briefly neutrinoless Double Beta Decay and discusses its implications for neutrino physics. After a presentation of general experimental concepts, such as the various proposed methodological approaches and the sensitivity, the current experimental situation is concisely reviewed.

[en] Three open problems in neutrino physics are mentioned. A brief review of neutrino- less double beta decay (DBD) is given. The question of quenching of g_A is discussed. Other possible scenarios, Majoron emission, sterile neutrinos and non-standard mechanisms, are presented and their implication to DBD discussed. (paper)

[en] There is a standard and 'common' scenario for the future of the neutrino experiments. The predicted region by the inverted mass hierarchy for the double beta decay may be reached in a few years and the CPV effects may be examined by a Megaton scale detector and a few MW of super-beams. But here we discuss one step beyond the standard scenario and consider how we can achieve such goals. We also investigate a possible modification of an existing detector for future experiments.

[en] Random coincidences of events could be one of the main sources of background in the search for neutrino-less double-beta decay of ${}^{100}$Mo with macro-bolometers, due to their modest time resolution. Scintillating bolometers as those based on Li${}_2$MoO${}_4$ crystals and employed in the CROSS and CUPID experiments can eventually exploit the coincident fast signal detected in a light detector to reduce this background. However, the scintillation provides a modest signal-to-noise ratio, making difficult a pile-up pulse-shape recognition and rejection at timescales shorter than a few ms. Neganov-Trofimov-Luke assisted light detectors (NTL-LDs) offer the possibility to effectively increase the signal-to-noise ratio, preserving a fast time-response, and enhance the capability of pile-up rejection via pulse shape analysis. In this article we present: (a) an experimental work performed with a Li${}_2$MoO${}_4$ scintillating bolometer, studied in the framework of the CROSS experiment, and utilizing a NTL-LD; (b) a simulation method to reproduce, synthetically, randomly coincident two-neutrino double-beta decay events; (c) a new analysis method based on a pulse-shape discrimination algorithm capable of providing high pile-up rejection efficiencies. We finally show how the NTL-LDs offer a balanced solution between performance and complexity to reach background index ∼10${}^{-<!--\; ???\; -->4}$ counts/keV/kg/year with 280 g Li${}_2$MoO${}_4$ (${}^{100}$Mo enriched) bolometers at 3034 keV, the Q${}_{\mathrm{\beta <!--\; ??\; -->}\mathrm{\beta <!--\; ??\; -->}}$ of the double-beta decay, and target the goal of a next generation experiment like CUPID.

[en] Neutrinoless Double Beta Decay (0νββ) is a rare nuclear transition that if it occurs at all it will be very important for the exploration of the inverted hierarchy region of the neutrino mass pattern. The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment that aims to search for such a transition in "1"3"0Te together with other rare processes. In the present paper we will describe the basic features of CUORE Experiment, the status of the experiment as well as the latest results obtained from CUORE-0 detector, a smaller scale experiment constructed to test and demonstrate the expected performances of CUORE.
