Expected sensitivity to test of standard solar models with future solar CNO neutrino flux measurement

Standard solar models built from spectroscopy and the helioseismology predicted inconsistent metallicity. Solar neutrino fluxes can be used to test two models. Hypothesis was performed using 7Be, 8B CNO fluxes. Current experimental results already disfavored low metallicity standard model at a significance of 2.1 σ. Considering new experiments that improve precision measured flux are being planned, it is important study their potentiality discriminating We evaluated expected reject where assumed central value uncertainty vary within range 3.5 × 108 -- 8 s−1cm−2 1%--20%, respectively. It found future strongly depends on measurement. When same as by Borexino in 2020, required reach 3 σ 5 20% 8%, respectively, which both achievable.
