论文摘要
与Lepton风味（$ L_E $，$L_μ$，$L_τ$）伴侣的矢量暗物质（VDM）类似于中微子风味特征状态的化学潜力，并修改了中微子的振荡。 VDM赋予了独特的特征，例如时间和方向依赖性，具有较长的基线，从而具有更好的敏感性。我们使用在Super-Kamiokande上对这种信号的非观察性来排除参数空间区域中VDM的存在，几个数量级以外的数量级以外的数量级，并显示了未来实验（例如沙丘）的预计覆盖范围。
Vector Dark Matter (VDM) that couples to lepton flavor ($L_e$, $L_μ$, $L_τ$) acts similarly to a chemical potential for the neutrino flavor eigenstates and modifies neutrino oscillations. VDM imparts unique signatures such as time and directional dependence with longer baselines giving better sensitivity. We use the non-observation of such a signal at Super-Kamiokande to rule out the existence of VDM in a region of parameter space several orders of magnitude beyond other constraints and show the projected reach of future experiments such as DUNE.
