Abstract

We report on a search for double beta decay of $^{130}$Te to the first$0^{+}$ excited state of $^{130}$Xe using a 9.8 kg$\cdot$yr exposure of$^{130}$Te collected with the CUORE-0 experiment. In this work we exploitdifferent topologies of coincident events to search for both the neutrinolessand two-neutrino double-decay modes. We find no evidence for either mode andplace lower bounds on the half-lives: $\tau^{0\nu}_{0^+}>7.9\cdot 10^{23}$ yrand $\tau^{2\nu}_{0^+}>2.4\cdot 10^{23}$ yr. Combining our results with thoseobtained by the CUORICINO experiment, we achieve the most stringent constraintsavailable for these processes: $\tau^{0\nu}_{0^+}>1.4\cdot 10^{24}$ yr and$\tau^{2\nu}_{0^+}>2.5\cdot 10^{23}$ yr.

Abstract

CUORE is a tonne-scale cryogenic detector operating at the Laboratori Nazionali del Gran Sasso (LNGS) that uses tellurium dioxide bolometers to search for neutrinoless double-beta decay of 130Te. CUORE is also suitable to search for low energy rare events such as solar axions or WIMP scattering, thanks to its ultra-low background and large target mass. However, to conduct such sensitive searches requires improving the energy threshold to 10 keV. In this paper, we describe the analysis techniques developed for the low energy analysis of CUORE-like detectors, using the data acquired from November 2013 to March 2015 by CUORE-0, a single-tower prototype designed to validate the assembly procedure and new cleaning techniques of CUORE. We explain the energy threshold optimization, continuous monitoring of the trigger efficiency, data and event selection, and energy calibration at low energies in detail. We also present the low energy background spectrum of CUORE-0 below 60keV. Finally, we report the sensitivity of CUORE to WIMP annual modulation using the CUORE-0 energy threshold and background, as well as an estimate of the uncertainty on the nuclear quenching factor from nuclear recoils inCUORE-0.

Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is designed to search for neutrinoless double beta decay of 130Te with an array of 988 TeO2 bolometers operating at temperatures around 10 mK. The experiment is currently being commissioned in Hall A of Laboratori Nazionali del Gran Sasso, Italy. The goal of CUORE is to reach a 90% C.L. exclusion sensitivity on the 130Te decay half-life of 9 × 1025 years after 5 years of data taking. The main issue to be addressed to accomplish this aim is the rate of background events in the region of interest, which must not be higher than 10- 2 counts/keV/kg/year. We developed a detailed Monte Carlo simulation, based on results from a campaign of material screening, radioassays, and bolometric measurements, to evaluate the expected background. This was used over the years to guide the construction strategies of the experiment and we use it here to project a background model for CUORE. In this paper we report the results of our study and our expectations for the background rate in the energy region where the peak signature of neutrinoless double beta decay of 130Te is expected.

Abstract

We report a study of the CUORE sensitivity to neutrinoless double beta (0) decay. We used a Bayesian analysis based on a toy Monte Carlo (MC) approach to extract the exclusion sensitivity to the 0 decay half-life (T1/20ν) at 90 % credibility interval (CI) – i.e. the interval containing the true value of T1/20ν with 90 % probability – and the 3σ discovery sensitivity. We consider various background levels and energy resolutions, and describe the influence of the data division in subsets with different background levels. If the background level and the energy resolution meet the expectation, CUORE will reach a 90 % CI exclusion sensitivity of 2 · 10 25 year with 3 months, and 9 · 10 25 year with 5 years of live time. Under the same conditions, the discovery sensitivity after 3 months and 5 years will be 7 · 10 24 year and 4 · 10 25 year, respectively.

Abstract

CUORE is a cryogenic detector that will be operated at LNGS to search for neutrinoless double beta decay (0ββ) of 130Te. The detector installation was completed in summer 2016. Before the installation, several cold runs were done to test the cryogenic system performance. In the last cold run the base temperature of 6.3mK was reached in stable condition. CUORE-0, a CUORE prototype, has proven the feasibility of CUORE, demonstrating that the target background of 0.01 counts/keV/kg/y and the energy resolution of 5 keV are within reach.

Abstract

We report on the measurement of the two-neutrino double-beta decay half-life of 130Te with the CUORE-0 detector. From an exposure of 33.4 kg year of TeO2, the half-life is determined to be T1/22ν = [8.2 ± 0.2 (stat.) ± 0.6 (syst.)] × 1020 year. This result is obtained after a detailed reconstruction of the sources responsible for the CUORE-0 counting rate, with a specific study of those contributing to the 130Te neutrinoless double-beta decay region of interest.

Abstract

The CUORE experiment will search for neutrinoless double-beta decay of 130Te with an array of 988 TeO2 bolometers arranged in 19 towers. CUORE-0, the first tower assembled according to the CUORE procedures, was built and commissioned at Laboratori Nazionali del Gran Sasso, and took data from March 2013 to March 2015. In this paper we describe the design, construction and operation of the CUORE-0 experiment, with an emphasis on the improvements made over a predecessor experiment, Cuoricino. In particular, we demonstrate with CUORE-0 data that the design goals of CUORE are within reach.

Abstract

We have performed a search for neutrinoless β+EC decay of Te120 using the final CUORE-0 data release. We describe a new analysis method for the simultaneous fit of signatures with different event topology, and of data subsets with different signal efficiency, obtaining a limit on the half-life of the decay of T1/2>1.6×1021 yr at 90% credibility interval (CI). Combining this with results from Cuoricino, a predecessor experiment, we obtain the strongest limit to date, corresponding to T1/2>2.7×1021 yr at 90% CI.
