Towards Dark Matter discovery with direct, production, and indirect searches

暗物质占宇宙物质的85%，其本质的发现被国际公认为是我们这个时代最重要的科学任务之一。目前正在研究三种互补的技术，以阐明这种难以捉摸的物质。直接搜索，如LUX和LZ实验，使用地下深处实验室的高灵敏度超低背景探测器，在地球目标中搜索银河系暗物质的罕见相互作用。加速器搜索试图重现大爆炸早期的条件，以产生新的暗物质粒子，这些粒子将在大型强子对撞机（LHC）上的ATLAS等探测器中留下特征缺失的能量特征或中介粒子的证据。间接搜索是利用高精度空间粒子探测器从星系和星系外来源寻找暗物质湮灭衰变产物的证据。这些互为补充的技术可能会在未来几年通过世界领先的实验带来首次探测。然而，目前还不清楚这些信号究竟是如何相互关联的，以及暗物质发现的可靠声明的准确性。该项目将探索现有结果对其他领域的影响，以约束暗物质模型的参数空间，并定义相空间，在此基础上，未来的极限或阳性检测可能会被集体映射。本研究对该领域具有重要意义；为了确定暗物质的发现，必须很好地描述三种搜索技术结果的相互关系。

Discovery of the nature of the Dark Matter, comprising 85% of the matter in the Universe, is internationally recognised as one of the highest scientific priorities of our time. Three complementary techniques are being pursued to shed light on this elusive substance. Direct searches such as the LUX and LZ experiments use highly sensitive ultra-low background detectors in deep underground laboratories to search for rare interactions of galactic Dark Matter in terrestrial targets. Accelerator searches attempt to recreate the conditions of the early Big Bang to produce new Dark Matter particles that would leave characteristic missing energy signatures or evidence of mediator particles in detectors such as ATLAS at the LHC. Indirect searches seek evidence of Dark Matter annihilation decay products from galactic and extra-galactic sources using high precision space-based particle detectors. These are complementary techniques that may bring first detections in the coming years through world-leading experiments. Currently, however, precisely how such signals would relate to one another, and the accuracy with which robust claims of discovery of Dark Matter could be claimed, is unclear. This project will explore the implications of existing results from each on the other fields to constrain the parameter space for Dark Matter models, and define the phase space upon which future limits or positive detections may be collectively mapped. This research is of considerable significance to the field; the interrelation of results from the three search techniques must be well characterised for definitive discovery of Dark Matter.
