论文摘要
暗物质是完整的自然理论的必要成分，到目前为止，在实验室寻找新粒子中仍然难以捉摸。在当前和未来的山脉上进行搜索原则上是搜索电动电荷的暗物质颗粒的有希望的方法，但是LHC和Future $ pp $ Colliders在LHC和Future $ pp $ collders的敏感性降低了，可以完全探测电动型电荷的带电的深色粒子的整个质量范围，这主要扩展到O（0.1）PEV。在这项工作中，我们研究了电荷电荷的热暗物质颗粒的壳和外壳繁殖对MUON撞机的几种标准模型最终状态的集成和差异速率的影响，考虑到在TEV量表上从弱的2次降低到O（0.1）pev ballpark scale的较弱的2次候选者。对于费米昂的wimps，我们发现所有具有$ n \ leq 5 $的暗物质候选者，对应于高达14 〜TEV的热量，在高能MUON撞机上可以排除在14〜TEV以下或以下的某些质量中心能量。对于$ n> 5 $ wimps，我们的结果表明，较高的能量宇航员山脉提供了一条途径，可以最终探测标量和费米子wimps of-shell生产，一直到O（0.1）〜PEV的WIMP暗物质的扰动。我们的结果带来了整个整个烟丝范围，允许对撞机搜索领域的质量范围，并激发了研究和开发，以实现高能量元对撞机。
Dark Matter is a necessary ingredient for a complete theory of Nature, which has so far remained elusive in laboratory searches for new particles. Searches at current and future colliders are in principle a promising way to search for electroweak charged dark matter particles, but the sensitivity of experiments at the LHC and future $pp$ colliders falls short to fully probe the whole mass range allowed for electroweak charged dark matter particles, which extends in principle up to the O(0.1) PeV. In this work we examine the effect of on-shell and off-shell propagation of electroweak charged thermal dark matter particles on integrated and differential rates of several Standard Model final states at the muon collider, considering candidates from weak 2-plet at the TeV scale up to 7-plet and 9-plet in the O(0.1) PeV ballpark. For fermionic WIMPs we find that all dark matter candidates with $n\leq 5$, corresponding to a thermal mass up to 14~TeV, can be excluded at the high-energy muon collider for some center-of-mass energy at or below 14~TeV. For the $n>5$ WIMPs our results show that higher energy muon colliders offer a route to conclusively probe both scalar and fermionic WIMPs off-shell production all the way up to the perturbativity bound for WIMP dark matter at O(0.1)~PeV. Our results bring WIMPs over the whole allowed mass range in the realm of collider searches and motivate research and development for the realization of a high energy muon collider.
