Abstract

The SNO+ collaboration reports its first spectral analysis of long-baseline reactor antineutrino oscillation using 114 tonne-years of data. Fitting the neutrino oscillation probability to the observed energy spectrum yields constraints on the neutrino mass-squared difference Δm212. In the ranges allowed by previous measurements, the best-fit Δm212 is (8.85-1.33+1.10) ×10-5eV2. This measurement is continuing in the next phases of SNO+ and is expected to surpass the present global precision on Δm212 with about three years of data.
