| Description |
<p>The SNO+ experiment will employ 780 tons of liquid scintillator loaded with 1.3 tons of 130Te (0.5% by mass) for a low-background and high-isotope-mass search for neutrino-less double beta decay. SNO+ uses the acrylic vessel and PMT array of the SNO detector with several experimental upgrades and necessary adaptations to fill with liquid scintillator. The SNO+ technique can be scaled up with a future high loading Phase II, able to probe to the bottom of the inverted hierarchy parameter space for effective Majorana mass. Low backgrounds and a low energy threshold allow SNO+ to also have other physics topics in its program, including geo- and reactor neutrinos, solar neutrinos, and searches for invisible modes of nucleon decay. This talk will present the first results of data collected in the water phase, providing a critical assessment of backgrounds for neutrinoless double beta decay.</p> |
