论文摘要
提出了拟议的船舶实验在CERN BEAM转储设施的现状。船是一种通用固定目标实验。从SPS中提取的400 GEV/$ C $质子梁将被倾倒在重型目标上，以在五年内将$ 2 \ times 10^{20} $质子整合在目标上。该检测器基于一个长的真空水箱，然后是光谱仪和粒子识别探测器，将允许探测各种模型，这些模型的长寿命长的外来颗粒和低于$ {\ cal O}（10）$ GEV/$ gev/$ c^2 $。主要的重点是所谓的隐藏门户的物理，即寻找深色光子，轻标量和伪量表以及沉重的中微子。对重中微子的敏感性将允许在Kaon和Charm Meson质量之间的质量范围内进行探测，这是一个耦合范围，该耦合范围也可以解释Baryogenogeny和活性中微子质量。第二个专用探测器将研究中微子并探索光线暗物质。
The current status of the proposed SHiP experiment at the CERN Beam Dump Facility is presented. SHiP is a general-purpose fixed-target experiment. The 400 GeV/$c$ proton beam extracted from the SPS will be dumped on a heavy target to integrate $2 \times 10^{20}$ protons on target in five years. The detector, based on a long vacuum tank followed by a spectrometer and particle identification detectors, will allow to probe a variety of models with light long-lived exotic particles and masses below ${\cal O}(10)$ GeV/$c^2$. The main focus will be the physics of the so-called hidden portals, i.e. the search for dark photons, light scalars and pseudo-scalars, and heavy neutrinos. The sensitivity to heavy neutrinos will allow to probe, in the mass range between the kaon and the charm meson mass, a coupling range for which baryogenesis and active neutrino masses could also be explained. A second dedicated detector will study neutrinos and explore light dark matter.
