Interpretation of First Detection of Solar Neutrinos from CNO Cycle with Borexino

Abstract

The Borexino collaboration observed an excess of the counting rate over the expected counting rate of events from CNO-ν. This result is consistent with the prediction of the Hydridic Earth Model on the contribution of 40K geo-antineutrino scattering on electrons to single Borexino events. The proportion of potassium in the Earth 1.5 ± 1.0% of the Earth’s mass is the most likely value that provides the observed excess of the counting rate.
