Quantitative Analyses

We investigate how the anticipated neutral current rate from SNO will sharpen our understanding of the solar neutrino anomaly. Quantitative analyses are performed with representative values of this rate in the expected range of 0.8–1.2. This would provide a 5–10σ signal for νe transition into a state containing an active neutrino component. Assuming this state to be purely active one can estimate both the 8 B neutrino flux and the νe survival probability to a much higher precision than currently possible. Finally the measured value of the NC rate will have profound implications for the mass and mixing parameters of the solar neutrino oscillation solution.

Neutrino Experiments

The combined effect of spin-flavor precession (SFP) and the nonstandard neutrino interaction (NSI) on the survival probability of solar electron neutrinos (assumed to be Dirac particles) is examined for various values ofϵ11,ϵ12, andμB. It is found that the neutrino survival probability curves affected by SFP and NSI effects individually for some values of the parameters (ϵ11,ϵ12, andμB) get close to the standard MSW curve when both effects are combined. Therefore, the combined effect of SFP and NSI needs to be taken into account when the solar electron neutrino data obtained by low energy solar neutrino experiments is investigated.

It is shown that the experiments on solar neutrinos can be accounted in terms of the Mikheyev-Smirnov-Wolfestein theory with ∆m2=6×10−6 eV 2 and sin 2 2θ=7×10−3. In the scenario proposed here the high energy neutrinos, from 8 B , have a survival probability around 1/3, the intermediate ones, around the 7 Be line a very small one ~ 2×10−3 and the low energy neutrinos, the ones coming from pp reactions, do not oscillate.
