论文摘要
我们在未来的TEV尺度MUON对撞机上提出了一个新的Beam Dump实验。梁垃圾场将是增加互补状态中对撞机复合物的发现潜力的经济和有效方法。在这项工作中，我们将矢量模型（例如深色光子和$l_μ-l_τ$ gauge玻色子）作为新的物理候选者，并探索可以使用MUON BEAM转储探测哪些新型参数空间区域。我们发现，对于黑暗光子模型，与现有和提出的实验相比，我们在较高和较低的耦合中获得了中等质量（MEV -GEV）范围的灵敏度，并访问了$L_μ -L_ -L_τ$模型的参数空间的先前未触及的区域。
We propose a new beam dump experiment at a future TeV-scale muon collider. A beam dump would be an economical and effective way to increase the discovery potential of the collider complex in a complementary regime. In this work we consider vector models such as the dark photon and $L_μ-L_τ$ gauge boson as new physics candidates and explore which novel regions of parameter space can be probed with a muon beam dump. We find that for the dark photon model, we gain sensitivity in the moderate mass (MeV - GeV) range at both higher and lower couplings compared to existing and proposed experiments, and gain access to previously untouched areas of parameter space of the $L_μ-L_τ$ model.
