Understand
CUORE-0 is a cryogenic detector that uses an array of tellurium dioxide bolometers to search for neutrinoless double-beta decay of ^{130}Te.
- We present the first data analysis with 7.1 kg y of total TeO_2 exposure focusing on background measurements and energy resolution.
- The background rates in the neutrinoless double-beta decay region of interest (2.47 to 2.57 MeV) and in the {\alpha} background-dominated region (2.70 to 3.90 MeV) have been measured to be 0.071 \pm 0.011 and 0.019 \pm 0.002 counts/keV/kg/y, respectively.
- The latter result represents a factor of 6 improvement from a predecessor experiment, Cuoricino.
