The main purpose of the Cryogenic Underground Observatory for Rare Events (CUORE) experiment is the search for the Neutrinoless Double Beta Decay (0νDBD) of 130 Te reaching a sensitivity on Majorana mass better than 50 meV. Cuoricino represents not only the first stage of CUORE, but also the most massive 0νDBD experiment presently running. Present results and future planning of these experiments will be described in the paper.

The CUORE (Cryogenic Underground Observatory for Rare Events) experiment will search for neutrinoless double beta decay of <sup>130</sup>Te, a rare nuclear process that, if observed, would demonstrate the Majorana nature of the neutrino and enable measurements of the effective Majorana mass. The CUORE setup consists of an array of 988 tellurium dioxide crystals, operated as bolometers, with a total mass of about 200 kg of <sup>130</sup>Te. The experiment is under construction at the Gran Sasso National Laboratory in Italy. As a first step towards CUORE, the first tower (CUORE-0) has been assembled and will soon be in operation.

The Cryogenic Underground Observatory for Rare Events (CUORE) is a tonne-scale cryogenic experiment located at the Laboratori Nazionali del Gran Sasso that exploits bolometric technique to search for neutrinoless double beta decay [Formula: see text] of [Formula: see text]Te. The detector consists of a segmented array of 988 natural [Formula: see text] cubic crystals arranged in a cylindrical compact structure of 19 towers. The detector construction was completed in August 2016 and data taking started in Spring 2017. In this work, we present a brief description of the bolometric technique for rare events search and the CUORE detector, then we concentrate on the data analysis results. In this respect, we focus on the procedure for data processing and on the first [Formula: see text] results we obtained from a total [Formula: see text] exposure of [Formula: see text]. Next, we illustrate the main background sources and the CUORE background model, from which we obtain the most precise measurement of [Formula: see text]Te [Formula: see text] half-life to date. Finally, we discuss the improvements achieved with 2018 and 2019 detector optimization campaigns and the current perspectives of our experiment.

The consequences of a texture zero at the ee entry of neutrino mass matrix in the flavor basis, which also implies a vanishing effective Majorana mass for neutrinoless double beta decay, have been studied for Majorana neutrinos. The neutrino parameter space under this condition has been constrained in the light of all available neutrino data including the CHOOZ bound on [Formula: see text].

Abstract The Neutrino Experiment with a Xenon TPC (NEXT) searches for the neutrinoless double-beta (0νββ) decay of 136Xe using high-pressure xenon gas TPCs with electroluminescent amplification. A scaled-up version of this technology with about 1 tonne of enriched xenon could reach in less than 5 years of operation a sensitivity to the half-life of 0νββ decay better than 1027 years, improving the current limits by at least one order of magnitude. This prediction is based on a well-understood background model dominated by radiogenic sources. The detector concept presented here represents a first step on a compelling path towards sensitivity to the parameter space defined by the inverted ordering of neutrino masses, and beyond.

The Germanium Detector Array (Gerda) is a low background experiment at the Laboratori Nazionali del Gran Sasso (LNGS) of the INFN designed to search for the rare neutrinoless double beta decay (0νββ) of76Ge. In its first phase, high purity germanium diodes inherited from the former Heidelberg-Moscow and Igexexperiments are operated “bare” and immersed in liquid argon, with an overall background environment of 10−2 cts/(keV·kg·yr), a factor of ten better than its predecessors. Measurements on two-neutrino double beta decay (2νββ) givingT1/22ν=(1.88±0.10)×1021 yrand recently published background model and pulse shape performances of the detectors are discussed in the paper. A new result on0νββhas been recently published with a half-life limit on0νββdecayT1/20ν>2.1×1025 yr(90% C.L.). A second phase of the experiment is scheduled to start during the year 2014, after a major upgrade shutdown. Thanks to the increased detector mass with new designed diodes and to the introduction of liquid argon instrumentation techniques, the experiment aims to reduce further the expected background to about 10−3 cts/(keV·kg·yr) and to improve the0νββsensitivity to aboutT1/20ν>1.5×1026 yr(90% C.L.).
