Analysis of the first data from the CUORE 0 νββ decay search
Abstract
CUORE-the Cryogenic Underground Observatory for Rare Events-is an experiment based at the Gran Sasso National Laboratories in Italy, searching for the neutrinoless double beta (0 νββ) decay of 130Te. A ton-scale bolometer consisting of 988 5 ×5 ×5 cm3 TeO2 crystals operated at 10 mK temperatures, CUORE began taking physics data in the spring of 2017. It is expected to achieve a 9 × 1025 year 130Te half life sensitivity (90 % C.L.) after a 5 year live time. We present an analysis of early data from the experiment, focusing on spectral line shape, resolution and background performance, as well as preliminary 0 νββ results.
