Description

The nature of neutrino masses is one of most important open questions in particle physics and has implications of physics beyond the standard model that could hint towards the observed particle-antiparticle asymmetry in the universe. Neutrinoless double-beta decay (0ννβ) is a very rare, hypothesized nuclear process, and is the only practical mechanism that could demonstrate if neutrinos have a Majorana nature. The Cryogenic Underground Observatory for Rare Events (CUORE) located at Laboratori Nazionali del Gran Sasso (LNGS) in Italy is the first ton-scale bolometer experiment that searches for neutrinoless double-beta decay in 130Te. CUORE started collecting data in 2017, and after operational upgrades in 2018, is stably operating with a current exposure of 724.3 kg-yr, with the aim of reaching 5 yr of live time. Using an exposure of 372.5 kg-yr, CUORE set a lower limit of 3.2×1025 yr (90% C.I) on the half-life of 130Te. In this talk, recent results from the latest CUORE analysis campaign will discussed. The current status of CUPID (CUORE Upgrade with Particle IDentification), the proposed experimental upgrade to CUORE, will also be discussed.
