The SNO+ experiment is a large multi-purpose neutrino experiment, located at a depth of 2km in a mine in Sudbury, Canada. Its primary physics goal is the search for the neutrinoless double-beta decay with 130Te.
After a first phase in which the SNO+ experiment operated as a water Cherenkov detector, as of April 2022 SNO+ is taking data with liquid scintillator as target material. The current phase allows the study of solar neutrinos, reactor and geo anti-neutrinos, as well as to measure the radioactive backgrounds prior to the tellurium loading. 3900 kg of natural tellurium (0.5% by weight) will be added to the scintillator in 2025, for a predicted sensitivity on the neutrinoless double-beta decay half-life of 130Te of about 2e26 years (90% CL) with 3 years of livetime. Higher tellurium loading will follow for predicted sensitivities above 1e27 years (3% loading).
In this talk I will focus on the current status of the experiment, its latest results, and the prospects for the neutrinoless double-beta decay search.
