Abstract
We report a preliminary result on the sensitivity and analysis techniques to search for double beta decay of 130Te to the first 0+ excited state of 130Xe in CUORE. With a TeO2 exposure of 369.9 kg ⋅ y, we find an expected limit setting sensitivity of y at 90 % C.I.
Highlights
CUORE is a ton-scale cryogenic bolometer array of 988 TeO2 cubic crystals operated underground at the Laboratori Nazionali del Gran Sasso (LNGS) of Istituto Nazionale di Fisica Nucleare (INFN), with the main aim of searching for the neutrinoless double beta decay (0νββ) of 130Te and other rare processes [1].The energy released by particle interactions in the crystals causes a temperature rise

The Monte Carlo (MC) simulations of the CUORE background sources allow to predict, for each signature, the expected background counts for the current available exposure of 369.9 kg · y
