论文摘要
我们建议对太阳中微子张力的可能解决方案，为什么太阳中微子在理论方面似乎与反应堆抗肿瘤有所不同。为此，基于添加了光无菌中微子的扩展理论，我们得出了中微子的一般过渡概率，其一种风味调整为不同的风味。扩展理论中增加了三个新的质谱差异：两个$δm^2 _ {\ rm abl} \ sillsim {\ cal o}（10^{ - 11}）\，{\ rm ev}^2 $在天文学基线（ABL）振动范围内进行了优化sbl} \ sim {\ cal o}（1）\，{\ rm ev}^2 $在反应堆短速率（SBL）振荡实验上进行了优化。具有所谓的复合物质效应，该效应通过正弦振荡（包括Mikheyev-Smirnov-Wolfenstein Matter效果）引起中微子风味的变化，我们发现可以从反应堆抗红体中测量的$δm^2 $的值与$^8 $ b solar中立实验的实验相提并论。 $Δm^2_1 \ sillsim10^{ - 13} \，{\ rm ev}^2 $和$Δm^2_2 \ simeq {\ cal o}（10^{ - 11}）\，{\ rm ev}^2 $。但是，我们发现当前的数据（仅太阳中微子）不够精确，无法测试所提出的方案。未来的$^8 $ b和$ pep $太阳中微子的精确度量可能会确认和/或提高$δ{m}^2_2 $的值。
We suggest a would-be solution to the solar neutrino tension why solar neutrinos appear to mix differently from reactor antineutrinos, in theoretical respect. To do that, based on an extended theory with light sterile neutrinos added we derive a general transition probability of neutrinos born with one flavor tuning into a different flavor. Three new mass-squared differences are augmented in the extended theory: two $Δm^2_{\rm ABL}\lesssim{\cal O}(10^{-11})\,{\rm eV}^2$ optimized at astronomical-scale baseline (ABL) oscillation experiments and one $Δm^2_{\rm SBL}\sim{\cal O}(1)\,{\rm eV}^2$ optimized at reactor short-baseline (SBL) oscillation experiments. With a so-called composite matter effect that causes a neutrino flavor change via the effects of sinusoidal oscillation including the Mikheyev-Smirnov-Wolfenstein matter effect, we find that the value of $Δm^2$ measured from reactor antineutrino experiments can be fitted with that from the $^8$B solar neutrino experiments for roughly $Δm^2_1\lesssim10^{-13}\,{\rm eV}^2$ and $Δm^2_2\simeq{\cal O}(10^{-11})\,{\rm eV}^2$. Nonetheless, we find that the current data (solar neutrino alone) is not precise enough to test the proposed scenario. Future precise measurements of $^8$B and $pep$ solar neutrinos may confirm and/or improve the value of $Δ{m}^2_2$.
