Improving CUORE Sensitivity using Multi-Site events

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton scale experimental search for neutrinoless double beta decay (0νββ) on ¹³⁰Te. The CUORE detector consists of 988 TeO₂ crystals operating as cryogenic bolometers at the Gran Sasso National Laboratory (LNGS) in Italy. While simulations suggest that about 11% of 0νββ decay events will deposit energy in more than one location, the most recent CUORE results come only from the analysis of single site events. In this talk, we present the projected sensitivity improvements achievable by using multi-site events that deposit energy in more than one crystal and the analysis techniques used to reconstruct the energy and estimate backgrounds.
