论文摘要
轻微的无菌中微子是在短碱基中微子实验中观察到的异常动机。在它们的情况下，放射性源和反应器实验分别提供了与EV级中微子兼容的电子中微子消失的证据和约束。这些观察结果的结果似乎正在发生冲突。该字母将焦点放在一个假设中，即中微子波包可以近似为平面波，这在此类实验的所有分析中都采用。我们证明了振荡的阻尼，例如由于有限的波数据包大小，可以解决这些电子料观测和约束之间的张力。
Light sterile neutrinos have been motivated by anomalies observed in short-baseline neutrino experiments.Among them, radioactive-source and reactor experiments have provided evidence and constraints, respectively, for electron neutrino disappearance compatible with an eV-scale neutrino. The results from these observations are seemingly in conflict. This letter brings into focus the assumption that the neutrino wave packet can be approximated as a plane wave, which is adopted in all analyses of such experiments. We demonstrate that the damping of oscillations, e.g., due to a finite wave packet size, solve the tension between these electron-flavor observations and constraints.
