Searching for Neutrinoless Double-Beta Decay and Beyond with CUORE

Abstract:

The worldwide quest to observe neutrinoless double-beta decay continues the long and successful history of using weak nuclear decays to explore the underlying properties of neutrinos, and search for new physics. CUORE, the Cryogenic Underground Observatory for Rare Events, is the first tonne-scale operating cryogenic neutrinoless double-beta decay experiment, instrumenting 742 kg of tellurium dioxide crystals at millikelvin temperatures. CUORE uses the cryogenic bolometer technique whereby temperature increases from particle energy deposition may be directly resolved with high resolution. With more than 2000 kilogram-years of detector exposure collected to-date, CUORE demonstrates the long-term stable operation of the technology at scale. In this talk, I will present recent searches for new physics with CUORE, including CUORE's latest search for neutrinoless double-beta decay in tellurium-130. Additionally, the analysis techniques and results from a search for an underground flux of fractionally-charged particles will be presented for the first time. Finally, I will discuss the future prospects of CUORE and its forthcoming successor, CUPID.
