太阳中微子问题及其可能的解释

Solar neutrino problems and their possible explanations

介绍了 2个太阳中微子问题和解决太阳中微子问题的几种可能解释 ,并详细讨论了太阳中微子振荡方案 .如果采用小混合角 (SMA)方案 ,那么 ,这 2种味的中微子的质量之差不超过 2 .32 378× 1 0 -3 eV ;如果用真空振荡 (VAC)方案 ,那么 ,这 2种味的中微子的质量之差不超过 8.94 42× 1 0 -6eV .认为如果中微子是暗物质的候选者 ,且中微子的静止质量要大于 1eV ,那么 2种中微子质量之差至多为 2 .7× 1 0 -6eV .

Two solar neutrino problems and some possible explanations were introduced in this paper. And the neutrino oscillation schemes were discussed in detail.If the small mixing-angle solution is adopted, the mass differences between two kinds of flavor neutrinos are not more than 2.323 78×10 + {-3 }eV; if the vacuum oscillation solution is adopted, the mass differences between two kinds of flavor neutrino are not more than 8.944 2×10 + {-6 }eV. If the neutrino is a candidate of dark matter with static mass more than 1eV, the mass differences between two kinds of flavor neutrino are not more than 2.7×10 + + {-6 }eV .
