论文摘要
我们分析了深地下中微子实验（Dune）对无菌中微子的敏感性，并结合了近距离检测器的信息。我们量化了经常被检测的效果，这可能会影响3+1振荡方案中事件速率估计。特别是，我们发现，与假设中微子的中微子来源相比，在中微子生产点上的信息会影响沙丘的无菌排除范围。在包含能量箱至无关的系统学之后，可见差异仍然存在。取而代之的是，实现近检测事件的精确振荡公式（包括两个平板密度谱）不会导致灵敏度的任何可见变化。
We analyze the sensitivity of the Deep Underground Neutrino Experiment (DUNE) to a sterile neutrino, combining information from both near and far detectors. We quantify often-neglected effects which may impact the event rate estimation in a 3+1 oscillation scenario. In particular, we find that taking into account the information on the neutrino production point, in contrast to assuming a pointlike neutrino source, affects DUNE's sterile exclusion reach. Visible differences remain after the inclusion of energy bin-to-bin uncorrelated systematics. Instead, implementing exact oscillation formulae for near detector events, including a two slab density profile, does not result in any visible change in the sensitivity.
