I will summarize in four slides the 40 years of development of the standard solar model that is used to predict solar neutrino fluxes and then describe the current uncertainties in the predictions. I will dispel the misconception that the p-p neutrino flux is determined by the solar luminosity and present a related formula that gives, in terms of the p-p and 7 Be neutrino fluxes, the ratio of the rates of the two primary ways of terminating the p-p fusion chain. I will also attempt to explain why it took so long, about three and a half decades, to reach a consensus view that new physics is being learned from solar neutrino experiments. Finally, I close with a personal confession and some personal remarks.

Solar Neutrino Experiment

AbstractThe observation of 8B solar Neutrinos in the Kamiokande-II detector is presented. Based on 450 days of data in the time period of January 1987 through May 1988, the measured flux obtained with Ee ≥ 9.3 MeV was 0.46 ± 0.13 (stat) ± 0.08 (sys) of the value predicted by the standard solar model. The detector and analysis methods were improved since June 1988 and the background level has been decreased by a factor of about three since then.

Flavor Mixing

We identify a plausible scenario based on quark–lepton symmetry which correlates long baseline oscillations with maximal mixing to sterile neutrinos. The implication for the Sudbury Neutrino Observatory (SNO) is that the neutral current signal will be found to suffer the same suppression from the standard solar model prediction as obtains for the charged current signal. Flavor mixing among active neutrinos is expected to occur on shorter baselines with smaller mixing amplitudes.

Good Agreement

The results of recent data from the 37 Cl , Kamiokande-II (K-II) and 71 Ga solar neutrino experiments are quantitatively analyzed. The results suggest that non-standard neutrino properties, instead of a non-standard solar model, are the correct explanation for the "solar neutrino problem." Assuming resonant neutrino oscillations, it is found that the "non-adiabatic" and "large angle" solutions are in quite good agreement with the data. The implications of these solutions for forthcoming solar neutrino experiments are discussed.

The latest Super-Kamiokande measurement of 8 B solar neutrino flux and recoil electron energy spectrum are presented. The highlights of our results are the day vs night flux asymmetry, which differs from zero at the 1.3 σ level, and the energy spectrum measurement, which shows no significant distortion compared to the BP98 standard solar model.

A closer look at the data collected from different detectors, reveal that the so-called solar neutrino problem is far from being solved. And contrary to the assessment of the Nobel Committee, the experimental results from the Sudbury Neutrino Observatory cannot be a confirmation of the Standard Solar Model. In fact, the obsoleteness of the current model has been recently exposed by the crisis of solar abundance. Furthermore, using images obtained by the Solar Dynamics Observatory, researchers found the convective motions (the plasma motions at the Sun's interior) to be nearly 100 times smaller than current theoretical expectations.
