Signature of the efficiency of solar nuclear reactions in the neutrino experiments

Abstract

In the framework of the neutrino oscillation scenario, we discuss the influence of the uncertainty on the efficiency of the neutrino emitting reactions 1H(p,e+ ν_e)2H and 7Be(p,γ)8B for the neutrino oscillation parameters. We consider solar models with zero-energy astrophysical S-factors S_11 and S_17 varied within nuclear physics uncertainties, and we test them by means of helioseismic data. We then analyse the neutrino mixing parameters and recoil electron spectra for the presently operating neutrino experiments and we predict the results which can be obtained from the recoil electron spectra in SNO and Borexino experiments. We suggest that it should be possible to determine tight bounds on S_17 from the results of the future neutrino experiment, in the case of matter-enhanced oscillations of active neutrinos.
