Several anomalies observed in short-baseline neutrino experiments suggest the existence of new light sterile neutrino species. In this review, we describe the potential role of long-baseline experiments in the searches of sterile neutrino properties and, in particular, the new CP-violation phases that appear in the enlarged 3 + 1 scheme. We also assess the impact of light sterile states on the discovery potential of long-baseline experiments of important targets such as the standard 3-flavor CP violation, the neutrino mass hierarchy, and the octant of ${\theta }_{23}$ .

在长期基线实验中探索轻质无菌中微子的评论

在短基线中微子实验中观察到的一些异常现象表明存在新的轻型无菌中微子物种。在这篇综述中，我们描述了长期基线实验在无菌中微子特性搜索中的潜在作用，特别是在扩大的3 + 1方案中出现的新的CP违反相。我们还评估了轻度无菌状态对重要目标的长基线实验（如标准的3味CP违规，中微子质量等级和辛烷值）的发现潜力的影响。 ${\theta }_{23}$ 。
