Abstract

The SNO+ Collaboration reports the first evidence of reactor antineutrinos in a Cherenkov detector. The nearest nuclear reactors are located 240~km away in Ontario, Canada. This analysis uses events with energies lower than in any previous analysis with a large water Cherenkov detector. Two analytical methods are used to distinguish reactor antineutrinos from background events in 190 days of data and yield consistent evidence for antineutrinos with a combined significance of 3.5$σ$.

    • Thanks! It's great to have both links, but in cases like this where the material is highly specialized (and not on a topic like computing that the audience here is familiar with), it's usually better to submit the best available popular article and then link to the paper in the…
