论文摘要
现代中微子探测器，特别是SBN和Dune的大型液体氩时间投影室（LAR TPC），提供了有关GEV规模相互作用的前所未有的信息。通过利用出色的空间和量热分辨率以及LAR TPC提供的低跟踪阈值，我们提出了一种新的方法，可以估算中性电流相互作用中中微子能量。该方法对寻找无菌中微子的潜在影响。它允许由于中微子中微子诱导的中微子中微子能量光谱中中微子诱导的振荡而引起的光谱畸变的潜在观察。例如，我们使用此方法在3+1模型下对SBN的中性电流通道中仅统计敏感性进行分析。
Modern neutrino detectors, particularly the large liquid argon time projection chambers (LAr TPCs) at SBN and DUNE, provide an unprecedented amount of information about GeV-scale interactions. By taking advantage of the excellent spatial and calorimetric resolution as well as the low tracking thresholds provided by LAr TPCs, we present a novel method of estimating the neutrino energy in neutral current interactions. This method has potential implications for the search for a sterile neutrino; it allows for the potential observation of spectral distortions due to sterile neutrino-induced oscillations in the neutral current neutrino energy spectrum. As an example, we use this method to perform an analysis of the statistics-only sensitivity to sterile neutrinos in the neutral current channel at SBN under a 3+1 model.
