Antineutrinos at SNO+

The SNO+ Experiment is a large liquid scintillator neutrino experiment located 2 km underground in Sudbury, Ontario, Canada. SNO+ is able to study a broad range of physics topics including reactor antineutrinos and geoneutrinos. The first detection of reactor antineutrinos in liquid scintillator at SNO+, as well as the current status of an updated analysis with a fully filled detector and increased livetime are presented. The analyses constrain the neutrino oscillation parameters Δm²₂₁ and θ₁₂, and will measure the flux of geoneutrinos at SNO+. Comparison of this result to previous measurements may help resolve tension between measurements of Δm²₂₁ from solar neutrinos and from reactor antineutrinos. Projections of the sensitivity to these parameters and to the geoneutrino signal with increased livetime are also presented.
