Searching for Neutrinoless Double-Beta Decay of Te-130 with CUORE

Abstract (for collaboration papers): 

Neutrinoless double-beta (0νββ) decay is a hypothesized lepton-number-violating process that offers the only known means of asserting the possible Majorana nature of neutrino mass. The Cryogenic Underground Observatory for Rare Events (CUORE) is an upcoming experiment designed to search for 0νββ decay of 130Te using an array of 988 TeO2 crystal bolometers operated at 10  mK. The detector will contain 206  kg of 130Te and have an average energy resolution of 5  keV; the projected 0νββ decay half-life sensitivity after five years of livetime is 1.6  × 1026  y at 1σ (9.5  × 1025 y at the 90% confidence level), which corresponds to an upper limit on the effective Majorana mass in the range 40–100  meV (50–130  meV). In this paper, we review the experimental techniques used in CUORE as well as its current status and anticipated physics reach.
