论文摘要
Faser $ν$是一个新提出的实验，将在2021 - 2023年期间在LHC的运行III中获取数据。它将位于FASER探测器的前面，距向前方向的Atlas相互作用点480 〜M。它的主要目标是检测在相互作用点产生的所有口味的中微子，在重建带电的轨道中具有出色的精度。此功能使Faser $ν$成为揭示浅色黑暗区域的模式和属性的理想设置。我们证明了这种能力良好类模型的能力，在几个GEV附近具有质量的暗物质候选者。暗物质将随后腐烂到标准模型带电费米子中的一对中间中性颗粒歼灭。我们展示了Faser $ν$如何通过在此类模型中揭示衰减链来阐明黑暗扇区的结构。
FASER$ν$ is a newly proposed experiment which will take data in run III of the LHC during 2021-2023. It will be located in front of the FASER detector, 480~m away from the ATLAS interaction point in the forward direction. Its main goal is to detect neutrinos of all flavors produced at the interaction point with superb precision in reconstructing charged tracks. This capability makes FASER$ν$ an ideal setup for uncovering the pattern and properties of a light dark sector. We demonstrate this capability for a well-motivated class of models with a dark matter candidate of mass around a few GeV. Dark matter annihilates to a pair of intermediate neutral particles that subsequently decay into the standard model charged fermions. We show how FASER$ν$ can shed light on the structure of the dark sector by unravelling the decay chain within such models.
