FASER，ForwArd Search Experiment，是一个拟议中的实验，致力于在LHC上寻找光，极弱相互作用的粒子。这种粒子可能在大型强子对撞机的高能碰撞中产生，在遥远的前方区域大量产生，然后在混凝土和岩石中长距离传播，而不发生相互作用。然后，它们可能在位于ATLAS相互作用点下游480米处的FASER中衰变为可见粒子。在这项工作中，我们描述的FASER计划。在其第一阶段，FASER是一个非常紧凑和廉价的探测器，对半径R = 10厘米和长度L = 1.5米的圆柱形区域内的衰变敏感。FASER计划在Long Han 2建造和安装，并将在2021-23年的14 TeV LHC运行3期间收集数据。如果FASER成功，FASER 2，一个更大的继任者，大约R ~ 1 m和L ~ 5 m，可以在Long Tour 3中建造，并在2026-35年的HL-LHC时代收集数据。FASER和FASER 2有可能发现暗光子、暗希格斯玻色子玻色子、重中性轻子、类轴子粒子和许多其他长寿命粒子，并提供有关中微子的新信息，对粒子物理学和宇宙学具有潜在的深远影响。我们描述了FASER计划的现状、预期挑战和发现前景。
英文摘要：
FASER, the ForwArd Search ExpeRiment, is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in the LHC's high-energy collisions in large numbers in the far-forward region and then travel long distances through concrete and rock without interacting. They may then decay to visible particles in FASER, which is placed 480 m downstream of the ATLAS interaction point. In this work, we describe the FASER program. In its first stage, FASER is an extremely compact and inexpensive detector, sensitive to decays in a cylindrical region of radius R = 10 cm and length L = 1.5 m. FASER is planned to be constructed and installed in Long Shutdown 2 and will collect data during Run 3 of the 14 TeV LHC from 2021-23. If FASER is successful, FASER 2, a much larger successor with roughly R ~ 1 m and L ~ 5 m, could be constructed in Long Shutdown 3 and collect data during the HL-LHC era from 2026-35. FASER and FASER 2 have the potential to discover dark photons, dark Higgs bosons, heavy neutral leptons, axion-like particles, and many other long-lived particles, as well as provide new information about neutrinos, with potentially far-ranging implications for particle physics and cosmology. We describe the current status, anticipated challenges, and discovery prospects of the FASER program.
