Description

The CUORE (Cryogenic Underground Observatory for Rare Events) experiment at Gran Sasso National Laboratory in Italy primarily searches for neutrinoless double-beta (0$\nu \beta \beta$) decay of ${}^{130}$Te. The CUORE detector consists of a close-packed array of 988 TeO${}_2$ calorimetric detectors cooled to below 15 mK using a custom-built cryogen-free dilution refrigerator. The experiment is the first to demonstrate stable operation of a tonne-scale milli-kelvin cryogenic calorimeter. We present the analysis framework used for the latest CUORE data release corresponding to over 2 tonne$\cdot$year TeO${}_2$ exposure. We focus on the improved signal processing and response modelling methods relative to our previous analysis, and the extraction of the 0$\nu \beta \beta$ decay result with a comprehensive overview of our coherent Bayesian approach.
