The SNO+ experiment: current status and future prospects — •Valentina Lozza — Institut fuer Kern- und Teilchenphysik, Zellescher Weg 19, 01069 Dresden, Germany
SNO+ is a large liquid scintillator based experiment that reuses the Sudbury Neutrino Observatory detector. The detector, located 2 km underground in a mine near Sudbury, Canada, consists of a 12 m diameter acrylic vessel which will be filled with 780 tonnes of liquid scintillator. The main physics goal of SNO+ is to search for the neutrinoless double-beta (0νββ) decay of 130Te. During the double-beta phase, the liquid scintillator will be initially loaded with 0.3–0.5% natural tellurium. In 5 years of data taking, SNO+ expects to reach a sensitivity on the effective Majorana neutrino mass of 55–133 meV, just above the inverted neutrino mass hierarchy region. Recently, the possibility to deploy up to 10 times more natural tellurium has been investigated, by which SNO+ could explore deep into the parameter space for the inverted hierarchy in the near future. Designed as a general purpose neutrino experiment, SNO+ can additionally measure the reactor antineutrino oscillations, geo-neutrinos in a geologically-interesting location, watch supernova neutrinos and measure low-energy solar neutrinos. A first commissioning phase with the detector filled with water will begin soon. The scintillator phase is expected to start after few months of water data taking. The 0νββ decay phase is foreseen for the 2017. In this talk the current status and the broad physics program of SNO+ will be presented.
