Abstract

Neutrinoless double beta decay (0νββ) is a rare, second-order nuclear transition that occurs only if neutrinos are massive Majorana particles or through new physics beyond Standard Model. This process explicitly violates the lepton number (L) by two units and, therefore, the observation of 0νββ would demonstrate that L is not a symmetry of nature. Combined with flavour mixing and cosmological measurements, it can provide unique contraints on neutrino mass scale and establish whether neutrinos are Dirac or Majorana particles. The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment located at the LNGS searching for 0νββ decay of ¹³⁰Te. CUORE exploits the bolometric technique to reach high resolution around the Q-value (2527.5 keV). It consists of an array of 988 natural TeO₂ cubic crystals grouped into 19 towers. With a total active mass of 742 kg (~206 kg of ¹³⁰Te), CUORE is operated at very low temperature with a new ³He/⁴He refrigerator. Data taking started at the beginning of 2017. After a brief introduction on the detector and the way data analysis is performed, I describe CUORE first results for the search of the 0νββ decay that were published in March 2018.

CUORE: The first bolometric experiment at the ton scale for the search for neutrino-less double beta decay

Journal Article Adams, D. Q. ; Alduino, C. ; Alfonso, K. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

The Cryogenic Underground Observatory for Rare Events (CUORE) is the most massive bolometric experiment searching for neutrino-less double beta (0νββ) decay. The detector consists of an array of 988 TeO₂ crystals (742 kg) arranged in a compact cylindrical structure of 19 towers. Here, this paper will describe the CUORE experiment, including the cryostat, and present the detector performance during the first year of running. Additional detail will describe the effort made in improving the energy resolution in the ¹³⁰Te 0νββ decay region of interest (ROI) and the suppression of backgrounds.

Results of CUORE

Journal Article - arXiv.org Repository

The Cryogenic Underground Observatory for Rare Events (CUORE) at the Laboratori Nazionali del Gran Sasso, Italy, is the world's largest bolometric experiment. The detector consists of an array of 988 TeO₂ crystals, for a total mass of 742 kg. CUORE is presently in data taking, searching for the neutrinoless double beta decay of ¹³⁰Te. CUORE is operational since the spring of 2017. The initial science run already allowed to provide the most stringent limit on the neutrinoless double beta decay half-life of ¹³⁰Te, and to perform the most precise measurement of the two-neutrino double beta decay half-life.

Searching for Neutrinoless Double-Beta Decay of ¹³⁰ Te with CUORE

Journal Article Artusa, D. R. ; Avignone, F. T. ; Azzolini, O. ; ... - Advances in High Energy Physics

Neutrinoless double-beta (0vββ) decay is a hypothesized lepton-number-violating process that offers the only known means of asserting the possible Majorana nature of neutrino mass. The Cryogenic Underground Observatory for Rare Events (CUORE) is an upcoming experiment designed to search for 0vββ decay of ¹³⁰Te using an array of 988 TeO₂ crystal bolometers operated at 10 mK. The detector will contain 206 kg of ¹³⁰Te and have an average energy resolution of 5 keV; the projected 0vββ decay half-life sensitivity after five years of livetime is 1.6 × 10²⁶ y at 1σ (9.5 × 10²⁵ y at the 90% confidence level),more »« less

CUORE-0 results and prospects for the CUORE experiment

Journal Article Cremonesi, O. ; Artusa, D. R. ; Avignone III, F. T. ; ... - AIP Conference Proceedings

With 741 kg of TeO₂ crystals and an excellent energy resolution of 5 keV (0.2%) at the region of interest, the CUORE (Cryogenic Underground Observatory for Rare Events) experiment aims at searching for neutrinoless double beta decay of ¹³⁰Te with unprecedented sensitivity. Expected to start data taking in 2015, CUORE is currently in an advanced construction phase at LNGS. CUORE projected neutrinoless double beta decay half-life sensitivity is 1.6 × 10²⁶ y at 1σ (9.5 × 10²⁵ y at the 90 % confidence level), in five years of live time, corresponding to an upper limit on the effective Majorana massmore »« less
