Abstract

Multi-boson productions can be exploited as novel probes either for standard model precision tests or new physics searches, and have become a popular research topic in ongoing LHC experiments and future collider studies, including those for electron–positron and muon–muon colliders. In this study, we focus on two examples, i.e.,

direct productions through

annihilation at a

muon collider, and

productions through vector boson scattering (VBS) at a

muon collider, with an integrated luminosity of

. Various channels are considered, including

and

+2jets. The expected significance on these multi-Z boson production processes is reported based on a detailed Monte Carlo study and signal background analysis. Sensitivities on anomalous gauge boson couplings are also presented.

在μ子对撞机上搜索多Z玻色子产生和反常规玻色子耦合* * 部分受国家自然科学基金（12150005、12075004、12061141002）和科技部（2018YFA0403900）资助

多玻色子的产生可以作为标准模型精确检验或新物理搜索的新探针，并已成为正在进行的大型强子对撞机实验和未来对撞机研究（包括电子-正电子对撞机和μ介子-μ介子对撞机的研究）的热门研究课题。在本研究中，我们重点讨论了两个例子，即在μ介子对撞机上通过湮灭直接产生和在μ介子对撞机上通过矢量玻色子散射（VBS）产生，其综合光度分别为......和......。我们考虑了各种渠道，包括和+2jets。根据详细的蒙特卡洛研究和信号背景分析，报告了这些多Z玻色子产生过程的预期意义。此外，还介绍了对反常规玻色子耦合的敏感性。
