摘要
COHERENT 实验凭借对相干弹性中微子-核散射（CEvNS）灵敏的低能反冲探测器，在由散裂中子源产生的 -DAR 中微子束中，处于测试亚 GeV 暗物模型的有利位置。我们展示计划中的 750-kg 液态氩闪烁探测器将如何在标量轻暗物质模型上放置领先的限制，在暗物质量的超过两个数量级范围内，针对通过矢量与轻 phobia 门户产生的暗物粒子（在标准模型之外无其他效应时）。-DAR 束的特征时间结构为在预期无信号的时窗中约束标准模型背景的系统不确定性提供了独特机会，从而增强预期灵敏度。此外，我们讨论了未来前景，进一步提升 CEvNS 探测器的发现潜力。此类方法将检验矢量门户模型内所有耦合 在暗物质量一个数量级范围内的计算热暗物丰度。
