论文摘要
几个中微子实验报告的结果可能与我们当前对Lepton部门的理解不一致。这些所谓的短基线异常的候选解决方案是假设存在新的，EV规模的，主要是无菌中微子，它们与活性中微子混合在一起。然而，一旦人们考虑了所有中微子数据，尤其是那些限制了短气素和电子中微子消失的假设，尤其是那些中微子的数据，就会强烈不利。在这里，我们表明，如果无菌活性混合参数取决于表征中微子产生和检测的能量量表，则无菌 - 中性假说可能会为所有中微子数据提供合理的拟合。改善拟合度的原因是，扩展中微子混合矩阵的不同元素的严格消失约束与与表征异常LSND和Miniboone外观数据的生产和检测能量量表有关。我们通过一个具体的例子表明，无菌中微子之间的秘密相互作用可以导致感兴趣的结果。
Several neutrino experiments have reported results that are potentially inconsistent with our current understanding of the lepton sector. A candidate solution to these so-called short-baseline anomalies is postulating the existence of new, eV-scale, mostly sterile neutrinos that mix with the active neutrinos. This hypothesis, however, is strongly disfavored once one considers all neutrino data, especially those that constrain the disappearance of muon and electron neutrinos at short-baselines. Here, we show that if the sterile-active mixing parameters depend on the energy-scales that characterize neutrino production and detection, the sterile-neutrino hypothesis may provide a reasonable fit to all neutrino data. The reason for the improved fit is that the stringent disappearance constraints on the different elements of the extended neutrino mixing matrix are associated to production and detection energy scales that are different from those that characterize the anomalous LSND and MiniBooNE appearance data. We show, via a concrete example, that secret interactions among the sterile neutrinos can lead to the results of interest.
