Background projections for CUPID

In the search for neutrinoless double beta decay, cryogenic calorimetric experiments play a fundamental role thanks to the possible use of different isotopes, the excellent energy resolution and the potential for particle identification. A major upgrade of the Cryogenic Underground Observatory for Rare Events (CUORE) is planned for the future, and denoted as CUPID: CUORE Upgrade with Particle Identification. In this talk, I will present the CUORE background model and, starting from this, expose the background predictions and sensitivity projections for various CUPID scenarios involving different isotopes.
