Abstract:
Neutrinoless double beta (NDB) decay is a hypothesized extremely rare decay, that could, among many other things, help explain the abundance of matter over anti-matter in the Universe around us. The Cryogenic Underground Observatory for Rare Events (CUORE) is a next-generation bolometric detector that will search for NDB decay and other rare processes. It is currently in the advanced stages of construction in the Gran Sasso National Laboratories in Italy. Its predecessor, Cuoricino, set the previous limits on the NDB decay half-life of 130Te, at T_1/2 > 2.8 x 10^24 yr (90% C.L.). CUORE will have an active mass nearly 19 times larger and an anticipated background about 16 times lower, providing a 1-sigma sensitivity to NDB decay half-life of T_1/2 > 1.6 x 10^26 yr after 5 years of live time. CUORE is expected to begin taking data in early 2016. The first phase of CUORE, called CUORE-0, was similar in size to Cuoricino and operated independently from 2013-2015. In this talk, I present the results of the CUORE-0 experiment, their implications for CUORE, and the new most stringent limits on NDB half-life of 130Te.
