Initial measurement of reactor antineutrino oscillation at SNO+
Year: 2025
Type: article
Abstract: 2 The SNO+ collaboration reports its first spectral analysis of long-baseline reactor antineutrino59 oscillation using 114 tonne-years of data. Fitting the neutrino oscillation probability to the observed60 energy spectrum yields constraints on the neutrino mass squared difference ∆m2 21. In the ranges61 allowed by previous measurements, the best-fit ∆m2 21 is (8.85+1.10 −1.33) × 10−5 eV2. This measurement62 is continuing in the next phases of SNO+ and is expected to surpass the present global precision on63 ∆m2 21 with about three years of data.
