Claims

C1strongest claim

We observe 5 single-peak and 1 double-peak neutrino-like events consistent with the 8B solar neutrino energy spectrum in the ROI after correcting for nonlinearities... With an expected background of 0.48 events, the data correspond to a significance of 4.0 sigma... energy-averaged cross section of (4.0 +2.0-1.6 stat +0.8-0.7 sys) x 10^-41 cm^2 ... a factor (2.4 +1.3-1.0) higher than predicted by Bhattacharya, Goodman and Garcia (2009).

C2weakest assumption

The background estimate of 0.48 +0.16-0.15 events and the assumption that the six observed events are produced by neutrino absorption rather than unmodeled backgrounds or detector artifacts after the high-energy nonlinearity corrections.

C3one line summary

DEAP-3600 provides 4-sigma evidence for 8B solar neutrino absorption on argon and measures a cross section 2.4 times above the Bhattacharya-Goodman-Garcia prediction.
