We report a study of the CUORE sensitivity to neutrinoless double beta (0νββ) decay.

Abstract

We report a study of the CUORE sensitivity to neutrinoless double beta (0νββ) decay. We used a Bayesian analysis based on a toy Monte Carlo (MC) approach to extract 0ν 0ν the exclusion sensitivity to the 0νββ decay half-life (T1/2) at 90% credibility interval (CI) – i.e. the interval containing the true value of T 0ν with 90% probability – and the 3 σ discov- 1/2 very sensitivity. We consider various background levels and energy resolutions, and describe the influence of the data division in subsets with different background levels. If the background level and the energy resolution meet the expec- tation, CUORE will reach a 90% CI exclusion sensitivity of 2 · 1025 year with 3 months, and 9 · 1025 year with 5 years of live time. Under the same conditions, the discovery sen- sitivity after 3 months and 5 years will be 7 · 1024 year and 4 · 1025 year, respectively.
