Solar neutrino studies and topological track reconstruction with the SNO+ experiment — •Johann Dittmer, Mikko Meyer, and Kai Zuber for the SNOplus collaboration — TU Dresden, Institut für Kern- und Teilchenphysik, Deutschland
SNO+ is a large liquid scintillator based experiment that reuses the Sudbury Neutrino Observatory (SNO). Located 2 km underground in a mine near Sudbury the detector consists of a 12 m diameter acrylic vessel which is filled with 780 t of liquid scintillator. Main goal of SNO+ is the search for the neutrinoless double beta decay (0νββ) of 130Te. The scintillator is loaded with 0.5 % by weight during the search. It is also possible to measure reactor–, geo–, supernova– and solar neutrinos.
This talk deals with the evaluation of expected background for 0νββ search coming from solar neutrinos detected via elastic neutrino–electron scattering (ES) and solar neutrino capture (ν–capture).
Furthermore, first results from the so–called topological track reconstruction developed in Hamburg will be presented. This method already demonstrated potential to discriminate background processes and might be an interesting tool for the analysis of solar neutrinos and the 0νββ search.
