CUORE-0 is a cryogenic detector that uses an array of tellurium dioxide bolometers to search for neutrinoless double-beta decay of (Formula presented.). We present the first data analysis with (Formula presented.) of total (Formula presented.) exposure focusing on background measurements and energy resolution. The background rates in the neutrinoless double-beta decay region of interest (2.47 to (Formula presented.)) and in the (Formula presented.) background-dominated region (2.70 to (Formula presented.)) have been measured to be (Formula presented.) and (Formula presented.), respectively. The latter result represents a factor of 6 improvement from a predecessor experiment, Cuoricino. The results verify our understanding of the background sources in CUORE-0, which is the basis of extrapolations to the full CUORE detector. The obtained energy resolution (full width at half maximum) in the region of interest is (Formula presented.). Based on the measured background rate and energy resolution in the region of interest, CUORE-0 half-life sensitivity is expected to surpass the observed lower bound of Cuoricino with one year of live time. © 2014 The Author(s).

Abstract

CUORE-0 is a cryogenic detector that uses an array of tellurium dioxide bolometers to search for neutrinoless double-beta decay of (Formula presented.). We present the first data analysis with (Formula presented.) of total (Formula presented.) exposure focusing on background measurements and energy resolution. The background rates in the neutrinoless double-beta decay region of interest (2.47 to (Formula presented.)) and in the (Formula presented.) background-dominated region (2.70 to (Formula presented.)) have been measured to be (Formula presented.) and (Formula presented.), respectively. The latter result represents a factor of 6 improvement from a predecessor experiment, Cuoricino. The results verify our understanding of the background sources in CUORE-0, which is the basis of extrapolations to the full CUORE detector. The obtained energy resolution (full width at half maximum) in the region of interest is (Formula presented.). Based on the measured background rate and energy resolution in the region of interest, CUORE-0 half-life sensitivity is expected to surpass the observed lower bound of Cuoricino with one year of live time. © 2014 The Author(s).
