Status of the CUORE and results from the CUORE-0 neutrinoless double beta decay experiments

TL;DR

This paper discusses the status and initial results of CUORE and CUORE-0 experiments, which aim to detect neutrinoless double beta decay of 130Te using bolometers, with CUORE-0 serving as a testbed for the larger CUORE detector.

Contribution

It reports the construction status, expected sensitivity, and initial data results of the CUORE and CUORE-0 experiments for neutrinoless double beta decay detection.

Findings

CUORE-0 started data collection in 2013.

CUORE aims for a background of 0.01 counts/keV/kg/y.

Projected half-life sensitivity of CUORE is 10^26 years in five years.

Abstract

CUORE is a 741 kg array of TeO2 bolometers for the search of neutrinoless double beta decay of 130Te. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts/keV/kg/y will be reached, in five years of data taking CUORE will have a 1 sigma half life sensitivity of 10E26 y. CUORE-0 is a smaller experiment constructed to test and demonstrate the performances expected for CUORE. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented.
