| | Neutrino Mass |
 | | All four solar neutrino experiments, Homestake [3], Kamiokande [4], SAGE [5], and GALLEX [6], observe a deficit of neutrinos compared to the standard solar model expectation [7], suggesting that there is either nonstandard astrophysics or new neutrino properties. |
 | | However, the relative rates observed by Homestake and Kamiokande yield a simple measure of the distortion of the spectral shape, suggesting that most of the suppression is in the middle of the spectrum, i.e. |
 | | Their rates are low compared to any reasonable solar model, standard or nonstandard, again suggesting the need for new neutrino properties. |
