论文摘要
太阳中微子实验对$^8 $ B中微子通量中的$ν\ to \overlineν$转换的来源高度敏感。在这项工作中，我们将这些搜索调整为最近提出的非最小无菌中微子模型，以解释LSND，MINIBOONE和反应堆异常。在阳光下的这种无菌中微子的产生遵循衰减链$ν_4\至νϕ \至νν\ to to newstalllineν$，带有新的标量$ ϕ $在每米级以每毫米级别的neutrino混合$ | u_ {e4} |^2 $ suft in Neutrino混合。我们得出的结论是，对所有异常的同时解释都与坎兰德，超级卡米卡德和鲍雷克西诺在太阳能抗肿瘤的通量上施加了张力。然后，我们提出其他最小模型，这些模型违反了奇偶校验或Lepton数字，并在每种情况下讨论我们约束的适用性。现有的Borexino数据以及添加GD的Super-Kamiokande的未来搜索可以预期未来的改进。
Solar neutrino experiments are highly sensitive to sources of $ν\to\overlineν$ conversions in the $^8$B neutrino flux. In this work we adapt these searches to non-minimal sterile neutrino models recently proposed to explain the LSND, MiniBooNE, and reactor anomalies. The production of such sterile neutrinos in the Sun, followed the decay chain $ν_4 \to νϕ\to νν\overlineν$ with a new scalar $ϕ$ results in upper limits for the neutrino mixing $|U_{e4}|^2$ at the per mille level. We conclude that a simultaneous explanations of all anomalies is in tension with KamLAND, Super-Kamiokande, and Borexino constraints on the flux of solar antineutrinos. We then present other minimal models that violate parity or lepton number, and discuss the applicability of our constraints in each case. Future improvements can be expected from existing Borexino data as well as from future searches at Super-Kamiokande with added Gd.
