Description
The Cryogenic Underground Observatory for Rare Events (CUORE) is a tonne scale detector searching for neutrinoless double beta decay ($0\nu\beta\beta$) in $^{130}$Te. The CUORE array is made of 988 TeO$_{2}$ crystals and operates at around 15 mK in the Gran Sasso National Laboratories (Italy).
Being the $0\nu\beta\beta$ a very rare process, every single background component has to be precisely understood. Material screenings and assays, together with a detailed Monte Carlo simulation, accomplish this essential and complex task, modeling the experimental background.
The CUORE background model reconstructs the data by means of a Bayesian fitting algorithm, estimating the contamination activities, measuring the half-life of decays such as the two neutrino double beta decay and allowing to put limits on other processes still to be observed.
The multi-segmented nature of CUORE instrinsically contains useful geometrical information related to the crystals and the surrounding setup. The granularity of CUORE can be extremely benefical to the performance of the background model: it can lead to a more precise source localization and a more mature description of the experimental setup, the same that will host a next generation experiment: CUPID.
In this contribution, I will discuss the strategy used to include topological data in the CUORE background model and the effects of this improvement on the global fit quality.
