摘要:

首次在大型强子对撞机(LHC)上直接探测到中微子,不仅开启了欧洲核子研究中心(CERN)全新的对撞机中微子研究计划,也推动学界考虑增设更多中微子探测器以充分挖掘相关物理潜力。我们研究了位于地面层面的中微子实验的可行性与物理潜力。通过地形案头研究,我们确定了LHC中微子束流穿出地球的所有点位,其中最近的位置位于CMS相互作用点以东约9公里处的日内瓦湖湖底。我们考虑了可部署在该位置的多种探测器,包括水切伦科夫探测器和核乳胶探测器。文中介绍了这些探测器的概念,并给出了它们对LHC前向中微子计划以及暗区粒子搜寻的贡献预期。不过,中微子流强随距离的衰减会显著降低中微子产额,与更靠近相互作用点的探测器(包括拟建的FPF)相比,地面层面探测器的物理潜力会受到限制。

英文摘要:

The first direct detection of neutrinos at the LHC not only marks the beginning of a novel collider neutrino program at CERN but also motivates considering additional neutrino detectors to fully exploit the associated physics potential. We investigate the feasibility and physics potential of neutrino experiments located at the surface-level. A topographic desk study was performed to identify all points at which the LHC's neutrino beams exit the earth. The closest location lies about 9 km east of the CMS interaction point, at the bottom of Lake Geneva. Several detectors to be placed at this location are considered, including a water Cherenkov detector and an emulsion detector. The detector concepts are introduced, and projections for their contribution to the LHC forward neutrino program and searches for dark sector particles are presented. However, the dilution of the neutrino flux over distance reduces the neutrino yield significantly, limiting the physics potential of surface-level detectors compared to ones closer to the interaction point, including the proposed FPF.
