Abstract
The theory of solar neutrino generation is reviewed with an emphasis on the measureable fluxes from the 8 B, 7 Be, and p− p reactions. The “solar neutrino problem” is summarized. It is emphasized that there are really two solar neutrino problems — the most compelling being the difficulty in making a quantitatively consistent picture of the relative rates of the different reactions from current experimental data. In addition, preliminary results from Super-Kamiokande are presented for the first 306 days of operation. The flux of solar neutrinos from 8 B is measured to be 2.44 ± 0.06( stat.) −0.09 +0.25( syst.) × 10 6 cm −2 s −1, inconsistent with the BP95 solar model prediction of 6.6 × 10 6 cm −2 s −1. No significant day/night or energy dependence is seen, although energy resolution will not reach the expected final value until on-going calibration studies with the electron LINAC are completed.
