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.
