论文摘要
我们研究了重轴状颗粒（ALP）的发现潜力，以及确定其在MUON对撞机上的偶联特性的观点。专注于他们与标准模型（SM）仪表玻色子$γ，z，w \ pm $ $的耦合，我们表明高能量的MUON撞机可以实质上扩展质量覆盖范围，从而实质上达到了对撞机能量的运动限制。独特的运动学允许非歧义确定单个耦合强度。可以利用$μ^+μ^ - $ nihihitation和带有标记的向外介子的VBF过程来验证阿尔卑斯山的CP属性。我们说明了在3 TEV和10 TEV上运行的MUON对撞机的结果。
We study the discovery potential for heavy axion-like particles (ALPs) and the perspectives for determining their coupling properties at a muon collider. Focusing on their couplings to the Standard Model (SM) gauge bosons $γ, Z, W^\pm$, we show that a high-energy muon collider can substantially extend the mass coverage, essentially reaching the kinematic limit of the collider energy. The unique kinematics allow for non-ambiguous determination of the individual coupling strengths. The associated production via $μ^+μ^-$ annihilation and the VBF processes with the tagged outgoing muons can be utilized to verify the CP property of the ALPs. We illustrate our results for a muon collider running at 3 TeV and 10 TeV.
