Model Independent Analysis of the Solar Neutrino Data

TL;DR

This paper conducts a comprehensive, model-independent analysis of solar neutrino data, confirming the disfavor of astrophysical solutions and revealing new insights into neutrino flux suppression patterns.

Contribution

It introduces a novel approach to analyze solar neutrino suppression, emphasizing the impact of neutrino flavor conversion on flux patterns.

Findings

Astrophysical solutions are highly disfavored.

Strong suppression of $^{7}$Be neutrinos is not supported when flavor conversion is considered.

Updated analysis includes high-statistics SuperKamiokande data.

Abstract

We perform an updated model-independent analysis using all the latest solar neutrino data, including the one coming from remarkably high statistics SuperKamiokande experiment. We confirm that the astrophysical solutions to the solar neutrino problem are extremely disfavored. We also present a new way of illuminating the suppression pattern of various solar neutrino flux, which indicates that the strong suppression of $^{7}$Be neutrinos is no more true once the neutrino flavor conversion is taken into account.
