Abstract

We have performed a search for neutrinoless β[superscript+] EC decay of [superscript 120]Te using the final CUORE-0 data release. We describe a new analysis method for the simultaneous fit of signatures with different event topology, and of data subsets with different signal efficiency, obtaining a limit on the half-life of the decay of T[subscript 1/2]>1.6×10[superscript 21] yr at 90% credibility interval (CI). Combining this with results from Cuoricino, a predecessor experiment, we obtain the strongest limit to date, corresponding to T[subscript 1/2]>2.7×10[superscript 21] yr at 90% CI.
