Title: μ子-希格斯耦合在高能μ子对撞机上的精度测试

Abstract: We explore the sensitivity of directly testing the muon-Higgs coupling at a high-energy muon collider. This is strongly motivated if there exists new physics that is not aligned with the Standard Model Yukawa interactions which are responsible for the fermion mass generation. We illustrate a few such examples for physics beyond the Standard Model. With the accidentally small value of the muon Yukawa coupling and its subtle role in the high-energy production of multiple (vector and Higgs) bosons, we show that it is possible to measure the muon-Higgs coupling to an accuracy of ten percent for a 10 TeV muon collider and a few percent for a 30 TeV machine by utilizing the three boson production, potentially sensitive to a new physics scale about $\Lambda \sim$ 30-100 TeV.

Abstract: 我们探讨在高能缪子对撞机上直接测试缪子-希格斯耦合的敏感性。 如果存在与标准模型的费米子质量生成相关的Yukawa相互作用不一致的新物理，这将具有很强的动机。 我们举例说明了一些超出标准模型的物理现象。 由于缪子Yukawa耦合的意外小值及其在高能多重（矢量和希格斯）玻色子产生中的微妙作用，我们表明，通过利用三玻色子产生，可以以10%的精度测量10 TeV缪子对撞机的缪子-希格斯耦合，而对于30 TeV机器则可以达到几%的精度，这可能对约$\Lambda \sim$30-100 TeV的新物理尺度敏感。
