论文摘要
由于高能量的虚拟电动Eletroweak（EW）仪表量表的高度孔子含量，高能量的高能量对撞机也是10 TEV周围和10 tev的质量能量。此功能与干净的环境一起使其成为搜索TEV尺度轴颗粒（ALP）耦合到标准型号EW量规玻色子的理想对撞机，而当前和其他未来的coll虫对此对此具有有限的敏感性。我们详细介绍了具有不同运行基准的MUON对撞机的VBF和相关生产渠道中重型ALP搜索的详细分析。我们还显示了有效场理论中对ALP耦合的预测约束，包括其系数未由混合Peccei-Quinn异常确定的操作员。我们证明，与HL-LHC相比，MUON对撞机可以探测新的ALP参数空间并推动ALP和EW量规玻色之间的耦合敏感性。预计的阿尔卑斯山的限制和搜索策略也可以应用于其他类型的共振耦合到EW仪表玻色子。
A high-energy muon collider with center-of-mass energy around and above 10 TeV is also a vector boson fusion (VBF) machine, due to the significant virtual electroweak (EW) gauge boson content of high-energy muon beams. This feature, together with the clean environment, makes it an ideal collider to search for TeV-scale axion-like particles (ALP) coupling to Standard Model EW gauge bosons, which current and other future colliders have limited sensitivities to. We present detailed analyses of heavy ALP searches in both the VBF and associated production channels at a muon collider with different running benchmarks. We also show projected constraints on the ALP couplings in the effective field theory, including an operator with its coefficient not determined by the mixed Peccei-Quinn anomaly. We demonstrate that a muon collider could probe new ALP parameter space and push the sensitivities of the couplings between the ALP and EW gauge bosons by one order of magnitude compared to HL-LHC. The projected limits and search strategies for ALPs could also be applied to other types of resonances coupling to EW gauge bosons.
