摘要
本文描述了 CERN SPS 上新建固定靶装置的物理意义。SHiP（Search for Hidden Particles，隐藏粒子搜索）实验旨在探索 LHC 实验无法触及的、费米能标以下弱相互作用粒子的大片未探索领域，并研究 τ 中微子物理。相同的质子束装置后续可用于寻找轻子味数不守恒的 τ 轻子衰变 ，以及搜索弱相互作用的亚 GeV 暗物质候选粒子。我们讨论了标准模型之外物理的证据，并描述了新粒子与四种不同媒介——标量、矢量、费米子或类轴子粒子——之间的相互作用。我们讨论了不同模型的动机，这些动机通过这些相互作用得以体现，以及如何通过 SHiP 实验进行探测，并给出了若干案例研究。还讨论了 SHiP 实验搜索相对轻的超对称粒子和复合粒子的前景。我们证明 SHiP 实验具有发现新物理的独特潜力，可以直接探测超出标准模型的若干谜题的解决方案，如中微子质量、宇宙重子不对称性、暗物质和暴胀。
