First data from CUORE-0

CUORE-0 is an experiment built to test and demonstrate the performance of the upcoming CUORE experiment. Composed of 52 TeO 2 bolometers of 750 g each, it is expected to reach a sensitivity to the 0νββ half-life of 130 Te around 3 · 10 24 y in one year of live time. We present the first data, corresponding to an exposure of 7.1 kg y. An analysis of the background indicates that the CUORE sensitivity goal is within reach, validating our techniques to reduce the α radioactivity of the detector.

Dark matter search with CUORE-0 and CUORE

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale experiment made of TeO₂ bolometers that will probe the neutrinoless double beta decay of ¹³⁰Te. Excellent energy resolution, low threshold and low background make CUORE sensitive to nuclear recoils, allowing a search for dark matter interactions. With a total mass of 741 kg of TeO₂, CUORE can search for an annual modulation of the counting rate at low energies. We present data obtained with CUORE-like detectors and the prospects for a dark matter search in CUORE-0, a 40-kg prototype, and CUORE.
