摘要
我们介绍了FP420研发项目，该项目研究了在距离ATLAS和CMS实验相互作用点420 m处的LHC隧道中安装硅径迹探测器和快时间探测器的关键方面。这些探测器与相应的中心探测器配合精确测量非常前向的质子，用以研究标准模型(SM)物理，并寻找和表征新物理信号。本报告详细描述了探测器的物理前景，特别是中心独占产生pp → p + φ + p的测量，其中出射质子保持完整，中心系统φ可以是单个粒子，如SM或MSSM Higgs玻色子。讨论的其他物理课题包括γ-γ和γ-p相互作用以及衍射过程。报告包含了对特定pp → p H p测量的触发策略、接收度、重建效率和预期产额的详细研究，其中Higgs玻色子衰变到b-bbar模式。文档还描述了由LHC束流光学给出的相互作用点与FP420位置之间的探测器接收度、机器本底、新的 proposed 连接低温恒温器以及420 m处的移动(汉堡)束管，以及设计对LHC的射频影响。文档最后一部分专门描述了三维硅传感器及相关跟踪性能、两个能够在高亮度下通过本底排斥进行精确顶点重建的快时间探测器的设计，以及探测器对准和刻度策略。
