Search for neutrinoless double-beta decay with SNO+

Abstract

The SNO+ experiment, located in SNOLAB, 2 kilometers underground in the Creighton mine, near Sudbury, Canada, is a large scale neutrino detector whose main purpose is to search for neutrinoless double-beta decay and thus probe the Majorana nature of the neutrino. With 780 tons of liquid scintillator loaded with tellurium, SNO+ aims at exploring the Majorana neutrino mass parameter space down to the inverted mass hierarchy region. The versatility of the SNO+ detector also allows it to detect solar and reactor neutrinos, provide a measurement of the geoneutrino flux, detect galactic core-collapse supernovae and perform nucleon decay searches. The SNO+ experiment is currently taking data with a detector fully filled with ultrapure water. The detector will be completely filled with liquid scintillator in the coming months and subsequently loaded with tellurium.
